Get SPO Tenant Site Collection Administrators list using CSOM.

Hi All,

I'm trying to get the list of all SCA's for a site collection created in SPO tenant.

using following code, i could able to view few properties of Site Collection but not the SCA's for that site collection.

spp = tenant.GetSiteProperties(startIndex, true);

Any other possibility to get the list of SCA's for a Site Collection created on SPO Tenant.

Thanks,

P
