We recently held an event on a platform whereby we had 12 breakout rooms . Each room had 1-2 presenters and various numbers of attendees. After an alotted amount of time, say 10minutes, all the participants were automatically moved into their next breakout room without them needing to click anything.
This was super useful and made our event a compete success and the user, competely hassle-free.
Please build this type of technology into Webex Breakout Rooms.
