    const [, data] = url.match(dataRegExp);
    const decodedData = JSON.parse(decodeURI(data));
    const { client } = this.props;

    if (decodedData.tokens) {
      await setItem('accessToken', decodedData.tokens.accessToken);
      await setItem('refreshToken', decodedData.tokens.refreshToken);

      await authentication.doLogin(client);
