batchDelete method
- GoogleAppsDriveLabelsV2BatchDeleteLabelPermissionsRequest request,
 - String parent, {
 - String? $fields,
 
Deletes Label permissions.
Permissions affect the Label resource as a whole, are not revisioned, and do not require publishing.
request - The metadata request object.
Request parameters:
parent - Required. The parent Label resource name shared by all
permissions being deleted. Format: labels/{label} If this is set, the
parent field in the UpdateLabelPermissionRequest messages must either be
empty or match this field.
Value must have pattern ^labels/\[^/\]+/revisions/\[^/\]+$.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a GoogleProtobufEmpty.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
Implementation
async.Future<GoogleProtobufEmpty> batchDelete(
  GoogleAppsDriveLabelsV2BatchDeleteLabelPermissionsRequest request,
  core.String parent, {
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'v2/' + core.Uri.encodeFull('$parent') + '/permissions:batchDelete';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return GoogleProtobufEmpty.fromJson(
      response_ as core.Map<core.String, core.dynamic>);
