If even this doesn't work, just send a screenshot of the options of the game in the steam client, I'm sure we will find a solution
So you donwload the game and in deskttop mode and then in desktop mode your going to left click and add non steam game go back to gaming mode and then go to the non steam game click on game icon settings and then go to conpatibility and us proton experimental or any other one and it should boot up and then just adjust the in game controls with the steam button and the game controller settings
