How to use navmesh unity navigation if map is generated dynamically?

Question

Unity

How to use unity's navmesh navigation if the map is created dynamically during the game. As I understand it, you need to download and use NavMeshComponents. For example, I tried this: generated a mesh, hung a NavMeshSurface on it, executed: surface.BuildNavMesh(); gives errors like: RuntimeNavMeshBuilder: Source mesh Plane139 does not allow read access. This will work in playmode in the editor but not in player UnityEngine.AI.NavMeshSurface:BuildNavMesh()
Has anyone done this?

Allow in mesh Read/WriteI think it's a bug.
