request - The metadata request object.
Request parameters:
initialGroupConfig - Optional. The initial configuration option for the
Group.
Possible string values are:
- "INITIAL_GROUP_CONFIG_UNSPECIFIED" : Default. Should not be used.
- "WITH_INITIAL_OWNER" : The end user making the request will be added as
the initial owner of the Group.
- "EMPTY" : An empty group is created without any initial owners. This can only be used by admins of the domain.

this method will complete with the same error.
Implementation
async.Future<Operation> create(
  Group request, {
  core.String? initialGroupConfig,
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if (initialGroupConfig != null)
      'initialGroupConfig': [initialGroupConfig],
    if ($fields != null) 'fields': [$fields],
  };
  const url_ = 'v1/groups';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return Operation.fromJson(response_ as core.Map<core.String, core.dynamic>);
