When an attendee is invited on stage he gets a " yellow hand raise sign " again at the bottom of the stage, clicking on which he gets out of the live stage, but still he can watch the session which is absolutely fine. But, This should be shown as " hands down " or  " leave tab " as it becomes clear to attendees that they can leave the stage using it and avoid confusion.
