Calling a Widget within a Widget (UE 4.27)

How do I call a widget from within a widget?

I’m trying to make a maze program in which the player clicks on one of four buttons to guide this robot to the goal. There is also a map button; when the button is clicked on, a map of the maze appears. When the player finds a room with a pit and falls in, the player is forced to restart and an additional icon is supposed to start appearing because its Boolean is then turned on.

But now, I can’t seem to make the widget with the clickable buttons reappear on the screen after a set of dialogue text from another widget finishes! So, from the dialogue text’s widget, what is the best way to make the movement widget reappear without having to use a Create Widget node?

Please provide screenshots as examples.
