What has your process been in trying to set this up so far? This will help determine what's got you stuck :)
Have you:
- Set up a navmesh and can see the coloured grid overlay
- Added the NPCs API from the scripts settings panel
- Got the worlds NavMeshManager in your script
- Got the NPC as an NpcPlayer in your script
Or is the issue more that you've got them to move but structuring code to "roam" is tricky?
I think the NPC API has changed recently, I've found the GenAI code to be out of date as far as NPCs are concerned.
