For each meeting, you get to choose if you want to use the same meeting space or create a new one and customize as needed.
A new meeting space (I control permissions)
This is a new meeting with a unique ID, and you get to customize permissions such as picking presenters (presenters have full control over the meeting), muting people, or blocking video sharing.
Tip: Just a heads up—this is a new meeting, so you’ll need to upload content or attach the files that you want to include.
My dedicated meeting space (less secure)
This is your own meeting space that will always have the same ID and permissions. Any content you attach, such as PowerPoint presentation or handouts, will stay with your meeting until you delete them. This meeting type is suitable for informal or recurring meetings with coworkers, and lets people sign in anytime with presenter permissions.
