WOW Classic Anniversary - New Steam controller getting only desktop inputs?

I'm trying to play wow classic with ConsolePort addon installed but no matter what i do the new steam controller seems to be registering mouse+keyboard inputs. Pressing A equals pressing enter.
I tried launching in big picture, with admin rights, adding battle net launcher as a non-steam game but i cannot get it work, i keep getting desktop inputs. I tried PS5 controller and X360 and they both work..
It seems the steam controller does not support x-input and this makes it so that every game must have its inputs translated by steam (steam input). Therefore, if the game is not properly setup on steam, the controller simply doesn't work at all. I tried everything i can to set it up through steam but it doesn't work..
Seems like a BIG oversight, i'm hoping they patch this. Can't believe i spent 99€ on a non-universal controller..

Has anyone encountered same difficulties? Got any fix?
