Hi
The package is currently hard coded to ignore triggers in all forms. Usually people never want them included in the graph. You could solve this by either making an actual collider, but change which layers it collides with, or you could use a GraphUpdateScene component (see graph update docs) as an alternative way of modifying the graph, or you could open the Base.cs script and find all instances of QueryTriggerInteraction.Ignore and change that to QueryTriggerInteraction.Collide or QueryTriggerInteraction.UseGlobal.
