delete method
Removes an alias.
Request parameters:
groupKey - Identifies the group in the API request. The value can be the
group's email address, group alias, or the unique group ID.
alias - The alias to be removed
$fields - Selector specifying which fields to include in a partial
response.
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<void> delete(
  core.String groupKey,
  core.String alias, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'admin/directory/v1/groups/' +
      commons.escapeVariable('$groupKey') +
      '/aliases/' +
      commons.escapeVariable('$alias');
  await _requester.request(
    url_,
    'DELETE',
    queryParams: queryParams_,
    downloadOptions: null,
  );
