Hello @Viki Ji_MSFT

I have below questions related to Co authoring

1. Does CSPP(cloud storage partner program) support the co authoring by default ? as property SupportsCoauth we need to set it true which is belongs to CSPP plus and I think which is paid.
2. as per https://learn.microsoft.com/en-us/microsoft-365/cloud-storage-partner-program/online/scenarios/coauth I can't see any such property details how to enable the co-authoring support

Thanks
