How to disable movement of Minimap?

Hi again, so I did what you said but I attached it to a close button on the ui and on my main BP . And this happens. I can open the UI switch through the captures, click the close button and then when i try to re-open the map by pressing tab. It won’t re-open, but shows the mouse again. Why is this? and how do I make the map open multiple times?
