I use Region To Share on Windows, and just drag windows on and off that virtual area as needed (works great with PowerToys FancyZones):

I haven't needed to do the same on a Mac yet, but if anyone knows of an app that does the same (i.e., define a "transparent" window that screen cap can then share in a call), do let me know (it's bound to be trickier on macOS due to window contexts, the compositor and privacy, but there might be an app out there for that)

Ah that's cleaner than my idea. Which was:

Install OBS, add a 'Scene', add a 'Window Capture' to the scene, then right click it (in sources) and transform / scale / crop the scene dimensions. Then optionally in the 'controls' panel you can start a virtual webcam, then go to Chrome/Brave settings, go to Site & Shield settings, set the default Camera to your virtual one.

Not sure if OBS would solve your Mac issue.

It wouldn’t really, since I don’t want to replace my camera feed—I just want sharing to share a region of the screen, like you do.
