 Room participants can be assigned one of the following roles: **Presenter**, **Attendee** and **Consumer**. By default, a user is assigned an **Consumer** role, if no other role is assigned.
 
 Participants with `Consumer` role will be receiving only the live stream. They will not be able to speak or share video or screen. Developers should not show the unmute, share video, and screen option to end users/consumers. Live stream supports both open and closed Rooms. In Open Rooms the default role is `Consumer`.
