Screen recording settings missing for some apps


So yeah, we're already telling our users that they will need to manually enable screen recording, disk access and many other settings now that they switched to Catalina. In fact, we're playing the privacy card and saying it's for their benefit.

But some apps (e.g. Google Chrome) sometimes are missing from the Screen Recording pane and there's no consistent way to make them appear there so the user can allow it.

Uninstalling and reinstalling Chrome (I blushed when I suggested it) helped a couple of times, but we have some other users that ended up needing to switch to another browser to share the screen in a Hangouts meeting.

Any ideas? Maybe a file we can delete so Chrome requests permission again.
