Of importance to note for security purposes: there are errors in the code. Notably, when registering your route use permission_callback (not permissions_callback with an ‘s’). A typo like that exposes your settings to the public, which you wouldn’t know unless you check your route while not logged in.

Thanks a lot 😉
