Request to Record Pop-up Not Appearing

Helping a client use a zoom app that records audio. It works on all machines (windows and mac) that I've tested, but the pop-up that says "[Blank] is requesting to record this meeting" does not appear for them. They are the host. We've gone through their settings and they match mine. It doesn't seem to be a Windows update problem (they're using Windows 10), as the app functions as expected with the pop-up coming through on Windows 10 and 11 machines. 

Anyone else run into this problem? Is there a setting that I'm maybe missing that they need to fix?
