How to correctly use the virtual keyboard

[tasptz]

I am trying to use the virtual keyboard in a qml based desktop application that may run in fullscreen or windowed mode.
The documentation does not make it clear to me how I do this right.

What I fiddled together now is:

// imports

ApplicationWindow  {

  // other components

  InputPanel {
    id: virtualKeyboard
    anchors.bottom: parent.bottom
    width: parent.width
    visible: InputContext.focus
    z: 10 
  }
}

In principle this behaves as I want it to. However the HideKeyboardKey does nothing.
So is this the intended way to use these qml components or am I on the wrong track? How would I catch if the HideKeyboardKey is pressed?

update
I can catch key presses with

            InputContext.inputEngine.virtualKeyClicked.connect(function (key, text, modifiers) {
              console.log('click ' + text)
            })

but the HideKeyboardKey does not trigger this signal.

I went through the whole documentation again and in the only available example there is a comment

/*  The visibility of the InputPanel can be bound to the Qt.inputMethod.visible property, ...

So I tried that and it works.

    InputPanel {
        anchors.bottom: parent.bottom
        width: parent.width
        visible: Qt.inputMethod.visible
        z: 10
    }
