How to make dynamic 3d Dialogue Speech Bubbles?

So i tried this tutorial which i used to create basic dialogues. But rather than displaying it to the UI, i wanted it as a speech bubbles like this, which follows the NPC and are interactive

However when i tried to recreate it using this tutorial, i see that only the widget dialogue that are interactive, while the 3d widget does not. This is what i mean by that: 2024-08-28 14-27-51.mp4 - Google Drive

Hi! Did You Solve this?

The examples he gives are screen space Interactive widgets which require an actor to have a Widget inside it, then a Widget Interaction inside the player character actor, off of Widget Interaction you need to get the click event and set it to Left Mouse Button if you want to have the mouse interact with buttons that are apart of the speech bubble widget (like the Speech Bubble Showcase video).
