How to scale/zoom a widget with blueprints?

Hi, if you don’t mind, could you explain how you make a point of interest to stay in the position of where it’s set on the map(the image) itself and move along with it? I’ve been trying to follow your method but instead of a point of interest, I want simple buttons to stay in position like it’s shown here. Currently, mine only remains in the same position of the viewport regardless of the map itself moving. Thank you very much, you’ve been a lifesaver so far.
