Help needed - Using scroll wheel to select inventory items BLUEPRINTS

Was wondering if anyone can point me in the right direction.
I have an inventory system with an array (used Ryan Laley’s UE5 tutorial, edited it a bit for my purposes).

Currently, I can pick up items and it records that data in the system and it displays correctly with UI widgets.

What I would like is a contextual menu - the inventory pops up when you use the scroll wheel, and cycles through the items, and selects whichever one you land on as the “Active” item.

Tried to find tutorials but nothing of much quality. If anyone has any pointers of how to do this, that would be great.

Main questions are
Using the enhanced mapping, should the scroll input use “Mouse Wheel Up” & “Mouse Wheel Down” or just “Mouse Wheel Axis”? Does it matter?
How to connect this input to hovering on different ItemSlots. I can get it that when it Starts the menu pops up but not sure how to go from there.

I hope that makes sense. If anyone needs any additional info to help let me know!
