Once breakout rooms are open, hosts and co-hosts can view the level of activity in each breakout room to get an idea of how active the participants are. On the Rooms tab in the Breakout Rooms panel, you can view which participants are in each room, along with icons that designate if their audio or video is on, if they're sharing their screen, and if they have any active reactions or nonverbal feedback. This feature can be particularly useful for instructors looking for student engagement in breakout room sessions.
