Doesn't show the widget when I press the button again

Hi, I’m making a pause menu. When I press Esc it shows the widget and when I press it once more it hides it, but after that I cannot display it anymore. I would like your help on how I can do this an infinite amount of times. I’m doing this in my level blueprint, because If I did it in my firstpersoncharacter bp than I could do it in every level, which I don’t want because I have a level called main menu and then those two widgets would overlay each other.

Here is the picture of my pause menu in level bp
