title: Can a saved Azure Spatial Anchor be saved(updated) again?
body: <p>I am wondering whether it is possible to 'update' a saved Azure Spatial Anchor. I created an anchor, saved it, then close the session, then start a new session, as I have the reference to the saved anchor(CloudSpatialAnchor object), I saved the anchor again in a different position, then I got this Exception:</p>

  <p>So, I assume it is not allowed to 'update' an anchor, the official document didn't mention it. If I get it right, we need to delete the anchor and then create a new one in the different position? Please confirm.</p>
