I'm running the latest beta version of GOG Galaxy and was wondering if the application only lists certain Rockstar Games.

I can run the Rockstar Games Launcher and it shows all the games I own, but the GOG Galaxy only lists GTA III, GTA Vice City, and GTA San Andreas. The application doesn't list GTA IV, GTA V, Bully: Scholarship Edition, L.A. Noire, Max Payne 3, Manhunt, and Red Dead Redemption 2.
