Automated UI and permission transitions between presenters of a communication session

A system provides automated transitions between presenters of a communication session. During a meeting, a system can provide a user interface that includes a primary presenter region configured to display a rendering of a presenter and the presenter's shared content. The user interface can also provide an audience region, which may include a number of individual video streams of audience members arranged in virtual environment. When the system determines that an individual audience member raises their hand, the system generates a graphical notification indicating that the person raised their hand. The system can also automatically add that individual audience member to a presenter queue. When the first presenter completes their presentation, the system can automatically transition the user listed in the presenter queue to the primary presenter region or a secondary presenter region. The system can also automatically change permissions for users that initiate a transition to a presenter role.
