WinUI 3 global key down/up events

I would like to handle the Escape button key pressed event in a WinUI 3 application, with MVVM Toolkit. I want to use this event to close the application.

I have tried different solutions, but most of them are talking about an UIElement which must have focus.
I have tried the Page KeyDown and KeyUp events, but they only trigger if there is an UIElement in the Page controls, which has focus.

In WPF I could do this by adding a MVVM command with parameter to a KeyBinding in the Windows.InputBindings.

Is there a way to obtain the same functionality in WinUI 3?

>Solution :

You can use KeybordAccelerators for this:

<Page.KeyboardAccelerators>
    <KeyboardAccelerator
        Key="Escape"
        Invoked="KeyboardAccelerator_Invoked"
        Modifiers="None" />
</Page.KeyboardAccelerators>

private void KeyboardAccelerator_Invoked(
    KeyboardAccelerator sender,
    KeyboardAcceleratorInvokedEventArgs args)
{
}

UPDATE

If you need to do your process via a command, you can use the Microsoft.Xaml.Behaviors.WinUI.Managed NuGet package.
