Is Possible To Use Spatial Anchors in PCVR?

I am able to get spatial anchors working standalone in the Quest 2, but when I try to get it working in while doing PCVR (using OpenXR), when I create an OVRSpatialAnchor, OVRSpatialAnchor.Created never returns true and it appears that OVRSpace is not initialized. Does anyone know if it is possible to use Spatial Anchors in PCVR?
