Thanks for the response! First things first, I got it going. I will walk you through my process for every launcher and then tell you what I did wrong. First the process I use:
- On steam in the bottom left press add a game and choose "Add non-steam game"
- Browse to this game's launcher file and select it (downloads folder, likely)
- Back In the steam library locate the new executable you just added, right click, click properties
- In the properties window, choose the Compatibility tab, check off "Force Compatibility" and select The latest NON-experiemental proton (9.0.4 as of now).
- Close out of properties, click play. Steam handles the rest
The mistake I made was a chose proton experimental, and subsequently the launcher opens but fails to download the files. So if anyone else is on linux and wants to play there's a step by step that works..
