Heroic Games Launcher supports GoG pretty well. You can install it with Flatpak using Discover in desktop mode.
When you login to GoG and install a game, you will be able to “Add it to Steam” (top-right hamburger menu in game’s view) and it should then be available in your “Non-steam games” in gaming mode.

Other options are Bottles and Lutris
Besides Flatpak, Heroic also has an official AppImage version, if the OP wants to have an even more portable program.
