How to get what navmesh a pawn is on

This may seem like a simple question, but I couldn’t find the answer.

How do I get the NavMesh that the pawn is on, in a level with multiple NavMeshes.

What I’m trying to do is get a random point on the NavMesh using GetRandomPointInNavigableRadius, but, I need to feed it a NavData var. I can get all Acrors of Class “Recast Nav Mesh”, but how do I cycle through them to find which one the Pawn is on?
Does the Pawn’s controller know?
