Future<void> logout() async {
  final lastToken = ref.read(currentFbMessagingTokenProvider);
  if (lastToken is String) {
    try {
      await removeUserFCMToken(lastToken);
    } catch (err) {
      _log.logCustom(UserMessagingRepositoryLog(
          'removeUserFCMToken', err, StackTrace.current));
