Application not listed in Control Panel after installation with Qt Installer Framework

[S_r_v]

QtIFW version: 4.10
Qt version: 6.9
OS: Windows 11 Pro (64-bit)

I created an installer using Qt Installer Framework (QtIFW) for my application let's say "Appl".
Everything installs correctly and the app runs fine.

However, when I install it to C:\Program Files (using @ApplicationsDir@),
the application does not appear in:

Control Panel → Programs and Features
Settings → Apps → Installed Apps

When I install to the user directory (e.g., @HomeDir@/), the app installs successfully and appears in both the places.

I Have Tried setting <RequiresAdminRights>true</RequiresAdminRights> in my package.xml and confirmed that the installer runs with admin privileges (UAC prompt shown) .Target directory is set to @ApplicationsDir@ and verified that the uninstaller (MaintenanceTool.exe) is created in the install folder but when checked under registry
given below entry is not created.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

There is only one component present.

</Package>

I am also attaching the corresponding packagescript.qs and configscript.qs
packagescript.qs

function Component()
{
    if (!installer.isCommandLineInstance())
        gui.pageWidgetByObjectName("LicenseAgreementPage").entered.connect(changeLicenseLabels);
}

changeLicenseLabels = function()
{
    page = gui.pageWidgetByObjectName("LicenseAgreementPage");
    page.AcceptLicenseLabel.setText("I agree");
}

Component.prototype.createOperations = function() {
    component.createOperations();

    var appExe = "@TargetDir@/appl.exe"; 
    var startMenuShortcutPath = "@AllUsersStartMenuProgramsPath@\\APPL\\APPL.lnk";

    component.addElevatedOperation("CreateShortcut", appExe, startMenuShortcutPath);
};

configscript.qs

function Controller() {
    installer.setDefaultPageVisible(QInstaller.StartMenuSelection, false);
}
Controller.prototype.ComponentSelectionPageCallback = function() {
    var page = gui.pageWidgetByObjectName("ComponentSelectionPage");
    page.title = "<div align='center'>Select Components</div>";

// funtion to disable NEXT button if no component is selected.
    function updateNextButtonState() {
            var components = installer.components();
            var anySelected = false;
            for (var i = 0; i < components.length; ++i) {
                if (components[i].isChecked()) {
                    anySelected = true;
                    break;
                }
            }
            gui.buttonById(QWizard.NextButton).enabled = anySelected;
        }

        gui.buttonById(QWizard.NextButton).enabled = false;
        installer.componentSelectionChanged.connect(updateNextButtonState);
        updateNextButtonState();

};

How can I ensure that Qt Installer Framework correctly registers the uninstaller, so the app appears in Control Panel / Programs and Features or Windows Settings → Installed Apps when installed to locations like C:\Program Files ?

Are there any additional step or metadata needed or did I miss anything?
