    Example code:
    1. // Find and enable the dynamic navigation mesh systemdynamicNavigationMeshSystem = Game.GameSystems.OfType<DynamicNavigationMeshSystem>().FirstOrDefault();dynamicNavigationMeshSystem.Enabled = true;// This stops the dynamic navigation mesh system from automatically rebuilding in the folowing cases://  - loading/Unloading scenes//  - adding/removing static collider components//  - adding/removing navigation mesh bounding boxesdynamicNavigationMeshSystem.AutomaticRebuild = false;// ...if (/* any condition that should cause the navigation mesh to update (eg open/close door) */){    // Start an asynchronous rebuild of the navigation mesh    var rebuildTask = dynamicNavigationMeshSystem.Rebuild();    rebuildTask.ContinueWith((x) =>    {        if (x.Result.Success)        {            // The navigation mesh is successfully rebuilt        }    });}
