How do I quit to the DMC HD Collection launcher?

I recently got my hands on the DMC HD Collection during the big steam sale right now and started with DMC1, issue is I can’t really get out of the game and back to the collection launcher.

Once I’m in the load game section after the main menu in DMC1 I can’t get back to the main menu. Can’t normally quit out of the game to the main menu when in or after a mission either, I must be overlooking something here right?

Am I just stupid or am I missing something (or both)?
