Steam itself does a lot of heavy lifting when it comes to controllers. Steam supports Playstation, Xbox, and Switch controllers on its own, even when the OS doesn’t.
Steam will usually hijack the built-in controller settings if you use the overlay and that’s actually a good thing except for a few corner cases. The windows application does not really care what’s on the other end because it’s presented with a “proper” DirectInput controller.
