Do you find yourself sitting in the Breakout Room, all alone, and you need to ask the Presenter a question? But the Presenter is not in the room with you. That is not a problem. You will be able to see the Host and Co-Presenters of the session listed in the Attendees List as long as they are still in the session.
When you need to send a Direct Chat to a Presenter, click the chat bubble next to the Presenter's name and the Chat box will change to a Direct Chat box.
