Anyone try gaming with an xbox or ps5 controller? Or mouse and keyboard?

I am wondering how the samsung xr works with an xbox series x controller or a ps5 controller over bluetooth. I might be willing to plug it into the headset if that's possible and better.

I know I need the samsung controllers for VR games, but I think I might use the samsung xr on a plane or something, and I might want to be able to try playing emulated games, or any game more suited for a regular controller.

Sort of related, I like the idea of a little keyboard: https://www.amazon.com/dp/B07T13GLY3/. But I'm also wondering how it would do paired with a mouse and keyboard for, say, an FPS game, or PC gaming using moonlight.
