On Windows, How Do You Get Zoom to Exit Full Screen and return to a Windowed Mode?

Once I enter full screen mode on Zoom, there seems to be no way to go back to a windowed view, which is standard for every program I've ever used, whether on Windows or Linux (in full screen mode, Zoom hides the menu bar that contains the min/max/exit icons).  For Zoom, full screen vs exit full screen is limited to controlling how Zoom presents the view within the Zoom window once it has already taken over the entire screen via Zoom's full screen option.   

What I want to know is how to get back to a windowed view in Zoom .  I have not found any Zoom doc on this.  Given that this is very basic functionality for any software app,  surely there must be a way.  Thanks.
