no longer interested in the operation result. It does not cancel the
operation. If the server doesn't support this method, it returns
google.rpc.Code.UNIMPLEMENTED.
Throws a http.ClientException if there were problems communicating with
the API service. Throws a StatusException if the API failed with a
Status message. Throws a ServiceException for any other failure.

final url = Uri.https(_host, '/v1/${request.name}');
await _client.delete(url);
}
