How to set the slidesPerView with partial slides on both ends using SwiperJS?

Question

Im new to SwiperJS. Right now my code is displaying 3 visible items with partial items on both sides. However I want 4 visible items on it instead of 3.

I don't know if theres something that I missed on swiper-api like slidesPerView, slidesPerGroup or anything else.

Check my code below:

var swiper2 = new Swiper(".mySwiperNav", {
  spaceBetween: 16,
  slidesPerView: 4.5,
  slidesPerGroup: 1,
  centeredSlides: true,
  loop: true,
  /*loopAdditionalSlides: 6,*/
  freeMode: true,
  watchSlidesProgress: true,
  allowTouchMove: true,
  keyboard: {
    enabled: true,
  },
  navigation: {
    nextEl: ".swiper-button-next",
    prevEl: ".swiper-button-prev",
  },
});
var swiper = new Swiper(".mySwiperFor", {
  spaceBetween: 16,
  effect: "fade",
  thumbs: {
    swiper: swiper2,
  },
});

.container, .container-lg, .container-md, .container-sm, .container-xl, .container-xxl {
  max-width: 1320px !important;
}

.swiper {
  width: 100%;
  height: 300px;
  margin-left: auto;
  margin-right: auto;
}

.swiper-slide img {
  display: block;
  width: 100%;
  height: 100%;
  object-fit: cover;
}

.mySwiperFor {
  height: 80%;
  width: 100%;
}

.mySwiperNav {
  height: 20%;
  box-sizing: border-box;
  padding: 10px 0;
}

.mySwiperNav .swiper-slide {
  width: 25%;
  height: 100%;
}

.mySwiperNav .swiper-wrapper {
  & .swiper-slide-visible:not(.swiper-slide-fully-visible) {
    opacity: .3;
    pointer-events: none;
  }
}
