Didn’t a Japanese company make a controller with native steam input? Is that controller any good? The thing with 8bitdo and the like is you can’t map back paddles to unique inputs via steam and they only can duplicate face buttons by programming the controller iirc.
I have a gulikit kk3, but I don’t love the dongle and don’t love the lack of native steam controller configuration for back paddles. Other than that, the hardware has been good for me.
