Showing Widget Via Button Press?

I’m currently trying to make an event so that when the player walks up to a paper on a desk, they can press a button to view a widget with a paper texture on it. I’m still a beginner to blueprints and don’t fully understand it so I’m sorry if my mistakes are obvious! I currently have a blueprint of a piece of paper with the model in it as well as a trigger volume, and a widget with an image of a piece of paper. I currently have this inside the paper blueprint but nothing happens
