Xbox Game Bar is very limited. It only captures a single window not the actual desktop, so you won't see any other window, dialog or context menu. I noticed it when I tried to record a demo of a git merge flow in an IDE. Fail! I wish this was properly built-in on Windows, since the recording is otherwise excellent.
