Only the meeting chair can grant and revoke permissions. If a meeting participant is granted permissions, they have permission to present content during a meeting; they also become a meeting "presenter." Be default, meetings allow everyone to present.
Permission to present lets individuals use the annotation tools to draw on the whiteboard and annotate slides, share a screen, and control the shared screen during a meeting. (The administrator determines which tools are available and if passing control of the shared screen is allowed.)
Anyone who has permission to present will see the Start Presenting button in the meeting room. Even with permission to present, you must click Start Presenting before you can work with slides or share your screen.
Chatting (either group or private chat), viewing sent Web pages, participating in polls, transferring files, and raising a hand do not require permissions. If a meeting includes these tools, all participants can use any of the tools at any time.
The participant who starts the breakout session is the chair. At the start of the meeting, all participants, including the chair, have all permissions. After the meeting starts, the chair can revoke and grant permissions.
The creator of the meeting selects the chair. The chair always has all permissions, but participants have permissions only If the meeting creator or chair grants them permissions either when the meeting is created or during the meeting.
The chair can grant and revoke permissions by clicking Set Permissions in the toolbar. All users in a meeting have permission to present content during a meeting by default. You can revoke the permission to present for all users, or grant permission to present to individuals in a meeting. You cannot revoke the chair's permission to present.
The chair can also right-click a person's name in the Attendee list during a meeting to display a menu and choose "Grant Permissions" to give that person permission to present or "Revoke Permissions" to remove permission to present.
Note The administrator determines what permission to present allows you to do. For example, the administrator can disable the ability to control the screen or use a whiteboard.
To see all participants who have permission to present during a meeting, click Show at the top of the Participant list and then select Presenters.
