UMG List - How do i go about using Tile View

I know this post is not really up to date but I can’t get it working properly for me. Can someone please explain to me how to:

  1. Implement the ‘GetListItemObject’ method by returning your new variable
  2. Implement the ‘OnListItemObjectSet’ method by setting your new variable to what is passed in
  3. Add your data to the TileView when you set it up (probably in PreConstruct with an array of data you need to view)

I get it working so far that it creates the Tile View on the right, but in the white square there should be a thumbnail from a pickaxe. But whatever I try it doesn’t show up.
