Use head (gaze) and controller to interact with Unity UI

I've been messing around for two days now and I still can't figure this out. I'm using 1.27 SDK and it seems I can only use the controller to interact with Unity UI. I did a small test with 12.6.1 and I've managed to get it working but clearly don't remember how.

I want to be able to use the controller and gaze look to interact with objects but it seems the input module only allows one.

Is this even possible? This is for Oculus Go.
