New UI Game Controller Button Selection

I have looked all over, and can’t really find anything. Can anyone point me in a direction that explains how to select buttons using an xbox controller and not a mouse when using the new UI system. I’ve been able to get the buttons highlighted with the controller, but I have to first click on of them with the mouse. I’m also still trying to figure out how to select the buttons with the controller, ie. press A to select as opposed to left clicking with the mouse.

Something that might help is if I was able to see the scripts attached to the new UI elements I tried to edit script but that wasn’t working, is there anywhere I can look at them and see whats going on?

I’m pretty new to UI, so this update came just in time for me.

I’m still trying to figure out how to do it but I did find this, hopefully I can find what I need here.
