There is actually no Co-Host in Video - that was a Meetings feature. Video only has a Moderator role. Either way, if the original Video meeting host needs to pass off control to another participant (either in a Moderator of Co-Host role), the participant who is assuming the new role needs to be able to manage Breakout Rooms AS WELL AS any other feature that the original Host can manage.

Currently only the host can manage breakout rooms - When we have large meetings, board meetings, or public forums on RCV it is extremely helpful to be able to have multiple of our admin staff help organize and run our larger meetings - when only the host can manage breakout rooms this makes using RCV compared to other video platforms with breakout rooms more difficult for our staff
