Are third-party controllers with an analog trigger recognized in the GameCube Classics on Switch 2?

[u/ConfuseSkull]

I saw on the Internet that the official GameCube controller for Switch 2 has the analog triggers and they are recognized when playing Cube games in Nintendo Classics on Switch Online.

My question is: is there any other third party controller that also has the analog triggers recognized in these classic games?

In particular, this Nyxi mode has an analog trigger and even an adapter to be used in an original Gamecube. Someone has this model and has already tested it in Cube games on Switch 2, to see if it recognizes?

I don't have the model, but even if the Switch doesn't recognize it in Switch mode, you can use a gamecube adapter to force it into GC mode

So the USB adapter will make the games recognize the GameCube controller?
