Great. Note looks like you are not familiar with GE? The installation is simple, just download the archive and unpack it under .local/share/Steam/compatibilitytools.d (or where your Steam is installed), so that you get something like .local/share/Steam/compatibilitytools.d/GE-Proton11-6-x86_64. Just unpacking the archive basically installs it. Restarting Steam is enough. There are tools that manage these custom Proton versions. I leave you a few relevant links:
- Proton GE: https://github.com/gloriouseggroll/proton-ge-custom
- Proton GE downloads: https://github.com/GloriousEggroll/proton-ge-custom/releases
- ProtonUp (to manage Proton versions and Proton GE): https://davidotek.github.io/protonup-qt/
It has additional fixes to Proton and is often more up to date. Some launchers such as Heroic Launcher I think integrate it too, so its usable outside Steam. I linked a gui tool to manage that, but you don't need a manager if you simply download and unpack the archive yourself.
Edit: And no I am not an Ai, lol I just noticed my reply sounded a bit robotic.
