How to use different slider plugin with Dynamic featured image?

I have already tried this steps: https://ankitpokhrel.com/explore/sliding-featured-image-thumbnails-in-your-wordpress-theme/. except the 5th.

Where I have to put this code?

jQuery(document).ready(function($){
$(‘.nivoSlider’).nivoSlider({
effect: ‘fade’, // Use any effect you want
directionNav: false, // We don’t need next and prev navigation
controlNav: false // 1,2,3… Navigation, we don’t need them too
});
});
