Spawning anad accessing a 3D Widget from Level Blueprint

Hi, Does anyone know if (and how) it’s possible to spawn a 3D widget from the Level Blueprint? I am trying to access variables from a 3d widget using the Level Blueprint and so far can’t find any viable solution to do this.
If I create a standard widget in a Level Blueprint and then refer to it, it works fine but my problem is accessing a 3D widget this way.
Basically, I want the Level blueprint to respond to a situation when a boolean in a 3d widget changes.

You can spawn the 3D widget like any actor. Did you already create an actor for your 3D widget?

Maybe you should take a few minutes to go through the example in the documentation…
