Cannot capture keydown event in a modal

Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• Angular: 13.2

Describe the bug
I am unable to capture the keydown event in a modal dialog.

The key press is coming from a hardware keyboard, not the onscreen one.

I can accomplish this in any other component using:

application.on('KEYCODE_DPAD_DOWN', (() => {
	console.log('Keyboard Down Arrow Pressed');
}));

And it works fine.

This is after extending activity.android.ts, and adding:

public dispatchKeyEvent(event) {
    let keyCode = event.getKeyCode();

    switch (keyCode) {
        case android.view.KeyEvent.KEYCODE_DPAD_LEFT:
        case android.view.KeyEvent.KEYCODE_DPAD_UP:
            application.notify({
                eventName: 'KEYCODE_DPAD_UP',
            })
            return true;
        case android.view.KeyEvent.KEYCODE_DPAD_RIGHT:
        case android.view.KeyEvent.KEYCODE_DPAD_DOWN:
            application.notify({
                eventName: 'KEYCODE_DPAD_DOWN',
            })
            return true;
        default:
            return super.dispatchKeyEvent(event);
    }
}

I have tried every manner of capturing the keypress in a modal that I could, none work.

To Reproduce
Extend android activity to capture a keypress, try to capture a keypress in a non-fullscreen modal.

Expected behavior
Should be able to capture the keypress and console log it, similar to how it is in a component.

Sample project

Additional context
In my modal, I have a dropdown. If I open the dropdown and then press the up/down arrow keys, it navigates through the selections, so the buttons work in the modal, I just don't know how to capture and console log them.

Please let me know if additional info is required.
