    //same as the auth config settings
    const stsSettings = {
      authority: "https://localhost:5000/",
      client_id: "AngularClient",
      scope: "openid profile api1 ",
      response_type: "code",
    };

    new Oidc.UserManager(stsSettings).signinSilentCallback().catch(error => {
      debugger;
      console.error("######## Silent call back -> ", error);
    });

  </script>
