Automatic Slider Option

I’m trying to follow the steps detailed in this topic:

https://wordpress.org/support/topic/how-do-i-get-the-slider-automatically-move?replies=9#post-7469224

But the “featured” file is not the same now, I’m using Hueman Version : 2.2.3 and here is what i found in my code:

jQuery('#flexslider-featured').flexslider({
animation: "slide",
useCSS: false, // Fix iPad flickering issue
directionNav: true,
controlNav: true,
pauseOnHover: true,
animationSpeed: 400,
smoothHeight: true,
touch: false,
slideshow: <?php if (ot_get_option('featured-slideshow') == 'on') { echo 'true'; } else { echo 'false'; } ?>,
slideshowSpeed: <?php echo ot_get_option('featured-slideshow-speed', 5000); ?>,
});
