list method
Lists the client-side encrypted identities for an authenticated user.
For administrators managing identities and keypairs for users in their
organization, requests require authorization with a
service account
that has [domain-wide delegation
authority](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority)
to impersonate users with the
https://www.googleapis.com/auth/gmail.settings.basic scope. For users
managing their own identities and keypairs, requests require
hardware key encryption
turned on and configured.
Request parameters:
userId - The requester's primary email address. To indicate the
authenticated user, you can use the special value me.
pageSize - The number of identities to return. If not provided, the page
size will default to 20 entries.
pageToken - Pagination token indicating which page of identities to
return. If the token is not supplied, then the API will return the first
page of results.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListCseIdentitiesResponse.
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.

  };
  final url_ =
      'gmail/v1/users/' +
      commons.escapeVariable('$userId') +
      '/settings/cse/identities';
  final response_ = await _requester.request(
