Magic Leap ARFoundation Anchor Subsystem does not implement TryAttachAnchor

I am working on porting my game on ARFoundation that works on ARKit/ARCore to Magic Leap. I ran into an issue where I call:

Code (CSharp):

1. ARAnchorManager.AttachAnchor(aRFoundationTrackedPlane.ARPlane, new Pose(trackedPlane.PlaneCenter, trackedPlane.Rotation));

And I get a null reference exception because Magic Leap does not implement the AttachAnchor API. An error should be returned instead of a null ref on a function call.
