[Solved] Can not for the life of me get WoW working with Lutris

Hello guys.

I am trying to play vanilla wow using private servers with lutris, and can't get anything to work properly.

I stumbled across this post which has people discussing this topic, but interestingly there is a link to github docs.

I follow the instructions in both this and this but even so, when I go through Lutris to add a game and select to search website for installers, then search for battle.net and follow the installation steps I get the error below:

I'm at my wits end. The closest I got was by directly running the WoW.exe file for a client I downloaded with wine from the terminal. The game started up without audio, and then obviously I wouldn't be able to put in my private server's credentials to log in. Please help me

EDIT: I ended up installing battle.net through bottles and I'm currently installing Diablo3 and Hearthstone - will see how they play.

As for WoW classic, whenever I run the 1.12 client I have in its own bottle it opens and then crashes. If I switch the runner to caffe it takes longer to crash, but my mouse seems to disappear when I take it over the launcher and I can't click on anything.

EDIT 2 SOLUTION: I skipped lutris/bottles altogether and as per a commenters suggestion I looked into adding it as a non-steam game to steam. It ended up working beautifully! Here is the video I watched that shows how to do it on a steam deck
