How to use the @openid/appauth/built/authorization_request_handler.AuthorizationNotifier function in @openid/appauth

constructor() {
    this.notifier = new AuthorizationNotifier();
    this.authStateEmitter = new AuthStateEmitter();
    this.authorizationHandler = new NodeBasedHandler();
    this.tokenHandler = new BaseTokenRequestHandler(requestor);
    // set notifier to deliver responses
    this.authorizationHandler.setAuthorizationNotifier(this.notifier);
    // set a listener to listen for authorization responses
    // make refresh and access token requests.
    this.notifier.setAuthorizationListener((request, response, error) => {
      log("Authorization request complete ", request, response, error);
      if (response) {
        this.makeRefreshTokenRequest(response.code)
          .then(result => this.performWithFreshTokens())
          .then(() => {
            this.authStateEmitter.emit(AuthStateEmitter.ON_TOKEN_RESPONSE);
            log("All Done.");
          });
