Main menu not being removed when game starts

Main menu level blueprint:

Main menu widget blueprint:

Didn’t work.

Get that variable, setted in screenshot 1, and toggle the visibility on event of screenshot 2.
PS.: I dont sure about that, but I thing there is a remove from viewport node, destroy or similar too.

Try this on main menu blue print: self → toggle Visibility

The levels do not change, how do I fix this.

What levels?
