Share Spatial Anchors - OpenXR Unity

Hi,

I'm trying to get Shared Spatial Anchors working using OpenXR instead of Oculus plugin. The reason I can't use Oculus is because other plugins are dependent on OpenXR. If I switch back to Oculus it works fine.

I can create anchors fine, but when it comes to sharing them, I get the following error:
Error OVRPlugin [SaveSpaceList] m_XR_FB_spatial_entity_storage_batch extension is not available (arvr/projects/integrations/OVRPlugin/Src/Util/CompositorOpenXR.cpp:12360)

Is there any workaround?

Thanks
