How do you check which input device is currently being used?

I want to be able to detect in realtime whether the player is using a gamepad (and which gamepad specifically i.e. xbox, dual shock, switch pro, etc.) or keyboard/mouse so I can display the correct control icons on-screen (such as showing A to interact if xbox, circle to interact if dual shock, F if keyboard, etc.).

I haven't been able to find good documentation on how to do this.

 

Inspect the gameobject that holds your Player Input component.
At the bottom it'll hold the input specifics of your player during play.
