 To rebake a ``NavigationMesh`` at runtime, use the NavigationRegion3D.bake_navigation_mesh() function.
 Another option is to use the NavigationMeshGenerator.bake() Singleton function with the NavigationMesh resource directly.
-If the navmesh resource is already prepared, the region can be updated with the NavigationServer3D API directly as well.
