When recording a meeting, record the screen that is being shared.
We just recorded a meeting for our team. No one used their cameras, but we were all watching someone's screen being shared to follow along with the code example. The recorded meeting only shows the icons of folks on the team, it does not show the screen we were all watching.

I tested it out and it worked for me. I recorded and then screen-shared my own screen, then had a coworker join me on a call, he shared his screen during recording, and it worked. Both audio and visual were recorded. However, the visual was quite a bit blurry.
