Fist Person Character Blueprint: widget behind widget

Hi. I possible to make a widget set in the First Person Character Viewport disappear and make another appear?
I mean I made them using Set Visibility Node but when the first one disappears I can’t control the other one.
Like the mouse cursor can’t overlap the first one.
I’ve made this video to show you what I mean…
