I added it in my application

   HorizontalLayout subjects = new HorizontalLayout();

    CountdownClock clock1 = new CountdownClock();
    Calendar c = Calendar.getInstance();
    c.set(2020, 11, 21, 0, 0, 0);
    clock1.setDate(c.getTime());
    clock1
            .setFormat("<span style='font: bold 13px Arial; margin: 10px'>"
                    + "Test Left<br />"
                    + " %d days, %h hours, %m minutes and %s seconds</span>");

    Iterator itr = buttons.iterator();
    while (itr.hasNext()){
        Button button = new Button(itr.next().toString());
        subjects.add(button);
    }

    addComponentAsFirst(clock1);

    add(subjects);
