QOAuth2AuthorizationCodeFlow and response

[CHIO-CHIO]

Hello!
I have some class for oauth2. When i launch, it open browser, i allow with terms, then it redirect me to page with auth code.

    this->oauth = new QOAuth2AuthorizationCodeFlow(this);
    connect(this->oauth, &QOAuth2AuthorizationCodeFlow::authorizeWithBrowser, &QDesktopServices::openUrl);


    const QUrl authUri(".../oauth/authorize");
    const auto clientId = "...";
    const QUrl tokenUri(".../oauth/token");
    const auto clientSecret("...");

    this->oauth->setAuthorizationUrl(authUri);
    this->oauth->setClientIdentifier(clientId);
    this->oauth->setAccessTokenUrl(tokenUri);
    this->oauth->setClientIdentifierSharedKey(clientSecret);

    this->oauth->setModifyParametersFunction([](QAbstractOAuth::Stage stage, QVariantMap* parameters) {
        (*parameters)["redirect_uri"] = QUrl("urn:ietf:wg:oauth:2.0:oob");
        if (stage == QAbstractOAuth::Stage::RequestingAuthorization) { //if permament
            parameters->insert("duration", "permanent");
        }
     });


    connect(this->oauth, &QOAuth2AuthorizationCodeFlow::statusChanged, [](QAbstractOAuth::Status status) {
        qDebug() << "Status accepted";
    });


    connect(this->oauth, &QOAuth2AuthorizationCodeFlow::granted, [=](){
        qDebug() << __FUNCTION__ << __LINE__ << "Access Granted!";
//        auto reply = this->oauth->get(whoami);
//        connect(reply, &QNetworkReply::finished, [reply](){
//            qDebug() << "REQUEST FINISHED. Error? " << (reply->error() != QNetworkReply::NoError);
//            qDebug() << reply->readAll();
//        });
    });

    this->oauth->grant();

But i dont recive any response/callback. Is there any wrong here?
