I just bought this and installed it using GOG Galaxy. I have a question about the Road to Elysium Pack that is included in the Deluxe Edition.

I can't tell if the expasion pack is installed or not - I think it is, but I am not sure. In GOG is just shows the Talos Principle 2 game. In GOG Galaxy, if I go into "Manage Installation" and select "Configure" then it does show with a check mark in the DLC tab (see attached picture). Does that mean it is installed?

Also, if it is installed then how do I access Road to Elysium expansion pack in the game? There does not seem to be any way to launch this expansion inside the main game, in Galaxy, or on my Windows 11 Start menu.
