Crashed in FF after receiving an answer to the 2nd question you can ask in stonks academy (and after asking the first). Sorry, lmk if there's bugtracker.
Some games ask for this macOS permission in order to provide a better full-screen experience by doing things such as preventing the top bar and dock from peeking or disabling certain shortcuts. Of course, it allows the game to function as a keylogger as well, which would be bad.
