There's a program called Lutris [0] that will handle GoG, Heroic will handle Epic [1]. Not sure about Twitch games, though, as I'm unfamiliar with their offering. If you mean Itch.io then Lutris handles that too.

it is possible to run Epic game store using lutris: https://lutris.net/games/epic-games-store/
There is also alternative launcher: https://github.com/Heroic-Games-Launcher/HeroicGamesLauncher
some games need more tinkering to run as versions in epic store seems to be less linux friendly
There is a client for Epic, Heroic (https://github.com/Heroic-Games-Launcher/HeroicGamesLauncher). EA and Ubisoft gave up on their walled gardens and sell their games via Steam now. There is still the EA Origin DRM client involved there somewhere and that can cause problems, but it can also work, so worth a try if the game is worth it.
