VR NPC Dialogue System

New to blueprints. Are there any good resources (online courses, tutorials, etc) for building sequential widget messages using a behavior tree in VR?
Essentially I have an NPC character with widget dialogue bubbles. I’d like to build a system where the VR Player can press the dialogue bubble that’s located in an NPC Blueprint and it changes the message in the dialogue bubbles. I’ve tried using desktop NPC dialogue tutorials that rely on the viewport and I’m having trouble adapting them.

Did you ever get an answer from someone?
I’m having a similar problem and feel like there are no resources for VR Dialogue systems in Unreal 5 (unless you buy from the marketplace which isn’t an option for me).
