I'm not 100% sure, but I believe you can somehow get it to work in Mint Cinnamon and another Linux program. I remember reading something like in a Reddit thread. Hopefully, you can come across it in there. 

1. Install Heroic Game Launcher
2. Install Proton GE
3. Add game´s .exe file to Heroic, select Proton GE as your translation layer
4. Enjoy
