How to initialize slick in ajax?

Question

JavaScript

When loading blocks via ajax and when clicking on them, a block with a slider is shown, images are not displayed in the slider at this moment.
Here is a part of the code with ajax in which I inserted the js code responsible for displaying the block with the slider

}).success(function(posts){
        page++;
        $("#ajax-posts").append(posts).slideDown('show'); // CHANGE THIS!
        $("#more_posts").attr("disabled",false);
        $("#more_posts").find("i").hide();

        jQuery('.sect_2_catalog a').on('click',function(){ ----- ЭТО ПРОИСХОДИТ КЛИКЕ ПО КНОПКЕ, КОТОРЫЙ ОТКРЫВАЕТ БЛОК СО СЛАЙДЕРОМ
          
          var scroll_el = jQuery(this).attr('href');

          if (jQuery(scroll_el).length != 0) {
            jQuery('.style_categor').slideUp(800);
            jQuery('.displFlex_none').addClass('acti');
            jQuery(scroll_el).slideDown(800); 
            jQuery('html, body').animate({ scrollTop: jQuery('.displFlex_none.acti').offset().top - 80 }, 1000);
          }

          return false;
          
        });
      });

Where and what should I write to initialize the slick slider, or what should I do to make the images appear in the slider
