How to request to record a meeting/Zoom class?

The requestor will need to ask the host either verbally or in the chat. If they grant you access, the host will need to navigate to the Manage Participants icon on the bottom of the screen, then click more next to the requestor's name, and finally click allow recording.  

If this is a Canvas configured Zoom meeting, the host/professor may or may not have the entire meeting set to record to share later.
