Autoplay Slides

Hi,
I want to autoplay the slides in a loop. The displayed image should been visible for a few seconds before the next one is visible. Is there any option in your theme or any code snippets to autoplay the slides?
I already tried with the following but its not working …

$('.slick-track').slick({
    draggable: true,
    autoplay: true,
    autoplaySpeed: 2000,
    infinite: true,
    slidesToShow: 1,
    slidesToScroll: 1,
    touchThreshold: 1000,
});

Best wishes
kedves
