Make key events output geometry

Need some help - trying to make the custom event node here output a geometry in real-time in Unreal, in game play mode.

Any ideas?

Appreciate it.

What do you mean output geometry? What do you want to achieve?

For example, if I hit a key on the keyboard, it creates a static mesh in the Unreal interface, in game mode.

Oh, the caveat to this is that it is using Coherent UI and the keyboard is a virtual keyboard on a web local host - any thoughts?
