How to change the width of active slide, when having slidesPerView: 3. (Swiper JS) if a change to auto, slides are not centered.

[Example on codepen] (https://codepen.io/salezr/pen/wvqLgzB)

var swiper = new Swiper(".mySwiper", {
      slidesPerView: "auto",
      centeredSlides: true,
      spaceBetween: 30,
      initialSlide: 1,
      pagination: {
          el: ".swiper-pagination",
          clickable: true
      }
});
