How do I use SpatialEntityStore to persist spatial mapping data and spatial anchors after a reset?
My goal is to back up the spatial mapping and spatial anchor data on a HoloLens so that if the HoloLens needs to be reset, the spatial mapping data and spatial anchors can be restored without forcing the user to re-scan an area or re-configure all the spatial anchors.
I found this article which seems to explain how to do this. https://developer.microsoft.com/en-us/windows/mixed-reality/shared_spatial_anchors_in_directx
However the referenced class (https://docs.microsoft.com/en-us/uwp/api/Windows.Perception.Spatial.SpatialAnchorTransferManager) says "The export/import approach of sharing spatial anchors between devices is being deprecated. In a future release of Windows, you will need to transition to the SpatialEntityStore API, which provides a shared pool of spatial anchors and metadata, which the system will synchronize on your behalf."
When I search for "SpatialEntityStore" (including quotes) on Google, I get 2 results. Where can I find examples of how to use a SpatialEntityStore to create a backup of spatial mapping data and spatial anchors?
