One thing I'll throw in to help with dependencies is that if you add a games installer as a non-steam game, set proton experimental compatibly, and when you run it will install all the dependencies you need.

Then, after install, edit the non-steam game you created to point the path to the game executable. You can't remove the game from steam for the installer and add a second one for the game because adding a non-steam game creates a steam managed folder that holds dependencies that will be deleted when you remove it. This you need to edit the game entry for the installer to point to the game executable inside that steam created folder.

Doing this I installed battle net, and then changed the path for the exec to the battle net launcher, and was able to play Blizzard games. For me I did it to get diablo 2 resurrected running for my kids on their steam decks, but I was super impressed by the proton compatibility layer.
