  • Panelists: Includes organizers, hosts, co-hosts, and speakers. By default, they can turn on their microphone and camera themselves, as well as share content independently.
  • Attendees: Cannot turn on their microphone or camera, nor share their screen, and can only see panelists' video screens. If an attendee wishes to speak, they can raise their hand to request to have their microphone turned on. In addition, attendees can not see each other's information in the Webinar video window.
Configure settings
Optionally, you can click Settings to change the following:
  • Settings: Set who can join, whether you want to use rehearsal mode, whether the panelists can start meetings, and whether the webinar will be automatically recorded. To learn more about rehearsal mode, see Use rehearsal mode in Lark Webinar.
  • Panelist/Attendee permissions: Set chat and sharing permissions.
  • Advanced options: Assign hosts to upcoming meetings in advance, add interpreters, and set a uniform virtual background for panelists. To learn how to set a uniform virtual background for panelists, visit Set a uniform virtual background in Lark Webinar.

After changing the settings, click Save in the upper-right corner, and then in the pop-up window, choose whether to send an update to event guests.
  • If you select Send, event guests will receive an update from the Calendar Assistant.
  • If you select Don't Send, event guests can only view the event updates in the calendar.
Start the webinar
Organizers/hosts can start a webinar directly from the event card. Organizers can also set whether to allow event panelists to start meetings beforehand.
  • If allowed, panelists can start a webinar.
  • If not allowed, event guests must wait for an organizer or host to start a meeting before they can join.

Manage permissions
In webinars, there are two different roles: panelists and attendees. Panelists include organizers, hosts, co-hosts, and general panelists. Different roles have different meeting permissions to ensure that meetings run smoothly, securely, and efficiently.
  • Hosts and co-hosts
  • Hosts and co-hosts can view the panelist or attendee list during the event, and they can also change the role of guests during a webinar.
  • Open the Participants list and select the participant whose role you want to change, then click the ··· More icon > Change Role to Panelist/Attendee to switch the participant's role.
  • 250px|700px|reset
  • Note: When a host or co-host changes an attendee into a panelist, the guest can choose for themselves whether they wish to change. When a host or co-host changes a panelist into an attendee, the guest will receive a notification: The host has changed your role to an attendee.
  • Panelists
  • During meetings, panelists can turn on their microphone and camera, and share their screen, as well as use interactions such as chat and reaction.
  • 250px|700px|reset
  • Attendees
  • During webinars, attendees can view panelists' camera screen, as well as any images they share, and interact using chat and reactions.
  • By default, attendees cannot turn on their microphone or camera, nor share their screen. In addition, attendees can not see each other's information in the Webinar video window.
  • If an attendee wants to speak, they can click Raise Hand on the action bar at the bottom; once a host grants them permission, they can click Unmute in the pop-up window to turn on their microphone.

Use stage mode
In a webinar, hosts and co-hosts can enable stage mode, as well as configure the background image and display layout for the stage area, and apply this display layout for all participants.
These features make it even easier to manage the layouts of large meetings. To learn more about using stage mode, visit Use stage mode in Lark Webinar.
View webinar data
After a webinar ends, the organizer will receive a notification from the Video Meeting Assistant with data about the webinar, such as how many people attended, the average view duration, and the number of live chat messages. For recorded webinars, the notification will include a link to the Minutes file.

Why do I show up as an attendee when using another device after a host changed my role from attendee to panelist during a meeting?
When your role is changed during a meeting, it will only take effect on the device you're currently using. If you join the meeting on another device, you will still have the role set for the event.
Why haven't I received a Meeting Assistant notification with the Minutes file link after a webinar has been recorded?
Once an organizer clicks to record during a webinar, a link to the minutes file will be sent along with the webinar data after the meeting ends. The link to the Recordings (Minutes) file is no longer sent separately.
After starting rehearsal mode, will the webinar automatically start at the scheduled time?
No, the webinar will only start after the host clicks Start Webinar.
Can a scheduled regular event be converted into a Webinar?
No.
Why don't I see the "Export Data Dashboard" button in the data card pushed after the meeting?
You can only export meeting statistics if the administrator has enabled this function. If needed, you can ask your administrator to enable the corresponding switch in the Lark Admin Console > Product Settings > Video Meetings > Meeting Settings section.

Can external users join my webinar?
Yes.
Can participants without login set their names in a webinar?
Yes. When joining a Webinar as a guest user from a web page, these anonymous participants can set their own names on the joining page. However, after clicking Join, anonymous or guest users can't modify their names during the webinar.
