You can give a guest additional permissions in your meeting by promoting them to the presenter role. Presenters can mute other guests. If you have restricted sharing capabilities to only you and presenters, presenters are able to share their screen, an application window, a file, or open a whiteboard. You can demote a presenter back to guest at any time.
Note: You cannot promote a VRC guest to presenter.
To promote a guest:
On the meeting sidebar, click the guest's name and select Promote.
The Presenter title appears above the guest's name and lets them mute other guests, share their own screen, share files, and open a whiteboard when open sharing is disabled.
