That’s it, Happy testing!
Regarding the documentation,
_api/webis for Sites, not SiteCollections. For SiteCollections it should be_api/sitehttps://learn.microsoft.com/en-us/sharepoint/dev/sp-add-ins/get-to-know-the-sharepoint-rest-service?tabs=csom#construct-rest-urls-to-access-sharepoint-resources
Unfortunately, the Site class doesn’t have this property. So, it wouldn’t work on the ‘_api/site’ endpoint.
Only the Web class has this property: https://learn.microsoft.com/en-us/dotnet/api/microsoft.sharepoint.client.web.memberscanshare?view=sharepoint-csom
That’s why I am using it on the (Root) Web of the Site Collection.
