Main menu event and getting uuid

The event you are looking for should be GuiOpendedEvent (or sth like that) there you should check if The opened gui is The Main Menu.

Have in mind that The player comes back to The Main Menu when logging out of a game, so you should check if your player is already logged in that 3rd Party thingy
