Restored window after minimizing is not maximized

Krakenus00

I'm trying to implement my own window frame for a desktop application. I have already done the borders and the top bar. There are only buttons what's left. So the problem is that my window restores windowed after minimizing even being at the Maximized state before minimizing.
Here is my code for buttons:
Maximizing button:

onReleased:
{
    mx_btn.highlighted = false
    if(app_window.visibility == 2) // Windowed
        app_window.showMaximized()
    else
        app_window.showNormal()
}

Minimizing button:

onReleased:
{
    mn_btn.highlighted = false
    app_window.showMinimized()
}

Application window props:

ApplicationWindow
{
    id: app_window
   
    ...

    flags: Qt.Window | Qt.FramelessWindowHint
    visible: true

    ...

    visibility: isFullWindow? Window.Maximized : Window.Windowed

    ...
}

I have no better idea than to rewrite all this stuff to QtWidgets with native support. I'll try to embed the main context using QML, but the window will be QtWidgets.

Omg, I've just ORed the flags, and now it works as intended.
In QtWidgets it should be:

	// To set the window minimized
	setWindowState(windowState() & ~Qt::WindowActive | Qt::WindowMinimized);
	// To restore the window from minimized state
	setWindowState(windowState() & ~Qt::WindowMinimized | Qt::WindowActive);

So in QML it should work in the same way.
