As a meeting host, you can pre-assign participants to breakout rooms when you schedule the meeting instead of managing them during the meeting. This can be useful if you already know how you want to split up your participants.
To enable the breakout room feature:
3. In the Meeting Options section, select Breakout Room pre-assign and click Create Rooms.
4. Click the plus icon beside Rooms to add breakout rooms.
5. In the Add participants text box, search for participants' name or email address to add them to the breakout room. Click Save.
