Webinar Breakout Rooms

I need some clarification on recording break out rooms, I was told

• If the webinar is being cloud recorded, it will only record the main webinar and none of the breakouts will be captured, regardless of what room the webinar host is in. Local recordings are also not supported in webinar breakout rooms.  - -i don't understand this? soo basically breakout rooms cannot be recorded, whether a cohost or host in in the room and even if its recorded on the computer?

Also, once participants are in the breakout rooms, do we have to unmute them so they can talk, or can they do it themselves?
