[6.5 LTS][Android] Qt app cannot know if the user rejected Bluetooth permissions, and cannot respond appropriately

#include <QApplication>
#include <QVBoxLayout>
#include <QPushButton>
#include <QBluetoothDeviceDiscoveryAgent>
#include <QPermissions>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QBluetoothPermission p;
    qDebug() << "Bluetooth permission status:" << app.checkPermission(p);

    QBluetoothDeviceDiscoveryAgent agent;
    QObject::connect(&agent, &QBluetoothDeviceDiscoveryAgent::deviceDiscovered, &app, [](const QBluetoothDeviceInfo& info){
        qDebug() << "Discovered device:" << info.name();
    });

    QWidget win;
    auto layout = new QVBoxLayout(&win);
    auto btn_req = new QPushButton ("Request Bluetooth Permissions");
    auto btn_scan = new QPushButton ("Start Scanning");
    layout->addWidget(btn_req);
    layout->addWidget(btn_scan);
    win.show();

    QObject::connect(btn_req, &QPushButton::clicked, &app, [&] {
        app.requestPermission(p, &app, [&]{
            qDebug() << "Permission requested.";
            qDebug() << "Bluetooth permission status:" << app.checkPermission(p);
        });
    });
    QObject::connect(btn_scan, &QPushButton::clicked, &app, [&] {
        agent.start();
        qDebug() << "Started trying to scan";
        qDebug() << "Bluetooth permission status:" << app.checkPermission(p);
    });

    return app.exec();
