I had the same problem (JamKazam not recognizing built-in camera for setup: MacBook with OS 10.125.4), but when I started a session, then clicked on the video button (which in my case was not grayed out), I received a dialog to grant permission for JamKazam to use the camera, which I granted, and camera (video) worked fine.
