Steam Link non-Steam game not recognizing controller

[UggJesus]

I have been using a Steam Link to stream games over LAN to my TV. Specifically, I have Xbox Game Pass Ultimate which includes many PC titles. This works fine if I use a keyboard and mouse plugged into the link and simply exit big picture mode then launch my game from the Xbox app. However, when I try to use my Xbox 360 controller with the same setup, the game does not recognize the controller as input.

The game I've been trying to play is Sunset Overdrive. I've followed instructions from this forum to create a .bat file which launches this game and added that as a non-Steam game and configured the Xbox controller from Big Picture Mode. This still results in the game not seeing the controller. Pressing the home button on the controller does not even bring up the overlay. I've also tried running Steam as admin as some have suggested as well as passing the controller device using virtualhere but none of these solutions seem to work. Anyone have any suggestions?

Here is the thread relating to adding the games as .bat files which call the launcher:
