Making Selectable UI Grid objects

Hi there,

I have a grid of ScriptableObjects in the UI that I want to make selectable for the player. However, while everything is setup and the ScriptableObject settings are working, I'm not sure how I can make my objects selectable. Right now, I'm trying to make my UI objects, which are housed under a Grid Layout Group in the Canvas clickable for testing purposes. However, ideally, I want to make the objects responsive to button presses (WASD and/or arrow keys) to select objects in the grid.

How do I make my UI grid objects selectable for the user?
