Scheduling Google Meet through Google Calendar Touring the Meet Room
Change ownership of a Calendar event - Did you now if you scheduled a calendar event you could change the owner of the event. This is particularly helpful if you were to do a meet but then could not make it. You could then open the calendar event, then select more actions (at the top) and scroll to the bottom and choose change owner. Put in the new owner. They will get an email and have to accept the invitation to make them owner. Now they will have host controls of the Meet.
