How to retrieve Shared Folder and Modifier information in /metadata call

I've edited out any tokens / unique identifiers with dashes. Let me know if you need the hashes or revs and I can open a private ticket.

This is the request from Fiddler:

GET https://api.dropbox.com/1/metadata/auto/Test?include_deleted=False&include_membership=True HTTP/1.1
Authorization: Bearer ---------------
Accept: application/json, application/xml, text/json, text/x-json, text/javascript, text/xml
User-Agent: RestSharp/104.4.0.0
Host: api.dropbox.com
Accept-Encoding: gzip, deflate
Connection: Keep-Alive

Here is the response:

HTTP/1.1 200 OK

         "mime_type":"text/plain",
         "revision":1617
      }
   ],
   "icon":"folder"
}

Thanks for the help.
