Simple VR Template toggle visibilty question

I’m learning VR in UE4. I’m using the Virtual Reality template for my project.
Now there is a simple thing I would like to do. If I “grab” a Cube an other object should toggle it’s visibility.
I’ve got it working that if I grab a cube the cube itself will toggle it’s visibility.

I’ve attached some screenshots of my scene and blueprint. How do I add a scene object to this blueprint and get it working?
I’ve been searching youtube and google for a while now but can’t find the answer.

Hope you guys can help me out with this very simple task.

ps: I’ve tried the same concept with the First Person Shooter template and got it working. I think becouse I did the setup in the Level Blueprint and
now it is in the Cube blueprint…
