Gamepad to focus on button/hover over button

Not sure where to start off. I have a setup where a menu of items is placed in a vertical box which is inside of a Scrollbox. I want to navigate up and down the vertical box to see the items in the item list menu as in Outer Worlds or Witcher 3, etc…

I have a setup but there’s nothing in terms of navigating the menu. I also have a scrollbox but again, no setup.

The two functions Move up and Move down don’t do anything because I have not set anything up yet for them.
