Setting keyboard focus to 3D Widget

I created a 3D Widget according to this tutorial:
And according to the tutorial added the widget as a component to my world.
So the component already exist in the world as a static component.
I am running this simple graph to get the focus but it does not get the focus to the buttons of my UMG menu.
Only after I click the menu area with the mouse, that the keyboard focus gets to the UMG buttons.
I am busting my head against the wall on this for a few days already.

Bump on this old topic. Does someone know how to make a 3d Widget Answer to keyboard & gamepad

I’m stuck on this at the moment, can’t get focus on 3D widget button with my controller.
