@NonNull
@Override

    Dialog dialog = super.onCreateDialog(savedInstanceState);

    // Here's the magic..
    try {
        // Set the dialog to not focusable (makes navigation ignore us adding the window)
        dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);

        // Show the dialog!
        dialog.setOnShowListener(dialogInterface -> {
            // Set the dialog to immersive
            dialog.getWindow().getDecorView().setSystemUiVisibility(dialog.getOwnerActivity().getWindow().getDecorView().getSystemUiVisibility());
