How to use Navmesh at ARFoundation scene?

Could I use Navmesh at AR scene?
I am trying to use Navmesh at gameobject as tracked images prefab.
It works on the editor.
But when I build for android, My character couldn't find the floor.
Should I use runtime nav mesh baking to slove this kind of problem?
If not , Anyone could give me any pointers?

 

I'd imagine you can ONLY use runtime navmesh baking since the floor isn't defined until you scan for the ARPlane. The visualizer prefab for the ARPlaneManager has a MeshCollider you can use to bake a navmesh.
