Different external urls for slides in slick slider?

Question

JavaScript

There is a slider (slick slider: kenwheeler.github.io/slick/)
Pictures as a background or slideshow are not used in it - mostly text. Something like this: wpfreeware.com/themes/html/singlepro/#team
( the template itself is not for WordPress - the link is just an example) slide in the slider (as is the default), but with, for example, the fifth slide specified in
the url (mysite.com?slide=5) mysite.com/5.
Here ( https://github.com/kenwheeler/slick/issues/152 - main discussion) and here ( jsfiddle.net/x6uo6c32/18- solution) it seems like there is a solution, but I have already broken my whole head and still nothing works.
HTML

JavaScript (custom.js) - didn't change anything in the minified slick.min.js.

$('.team_slider').slick({
      dots: false,
      infinite: true,
      speed: 300,
      slidesToShow: 1,
      slidesToScroll: 1,
      responsive: [
        {
          breakpoint: 1024,
          settings: {
            slidesToShow: 1,
            slidesToScroll: 1,
            infinite: true,
            dots: true
          }
        },
        {
          breakpoint: 600,
          settings: {
            slidesToShow: 1,
            slidesToScroll: 1
          }
        },
        {
          breakpoint: 480,
          settings: {
            slidesToShow: 1,
            slidesToScroll: 1
          }
        }
      ]
    });

How to win? Thank you.

Slick has an initialSlide property to specify the initial slide.
A from url can be taken like this (for the mysite.com/5 option):

var slideNum = 0;
var tmp = document.location.pathname.match(/^\/(\d+)/);
if (tmp && tmp[1]) slideNum = tmp[1];

Or so, for the first option (mysite.com?slide=5):

var slideNum = 0;
var tmp = document.location.search.match(/slide=(\d+)/);
if (tmp && tmp[1]) slideNum = tmp[1];
