How to use the auth0-lock.Auth0Lock function in auth0-lock

super();

    const params = {
      autoclose: true,
      oidcConformant: true,
      auth: {
        audience: `${Config.API_BASE_URL}`,
        params: {
          scope: 'openid profile email'
        },
        responseType: 'token'
      }
    };

    // Instantiate the Auth0Lock library
    const lock = new Auth0Lock(
      Config.AUTH0_CLIENT_ID,
      Config.AUTH0_DOMAIN,
      params
    );
    this.lock = lock;

    // Listen for the authenticated event on the Auth0 lock library and call the 
    // onAuthenticated method
    this.lock.on('authenticated', this.onAuthentication)
  }
