Removing div/divs if attribute already exists in another div

Im trying to get function that will delete div/s with attributte that already exists and leave 1 left so there will be no copies of that.

function favoriteLoadItems() {

  const resultsFAV = document.querySelector(".library-favorite-container");
  var favoritIt = allMusic.filter(x => x.status === "favorite");
  for (let i = 0; i < favoritIt.length; i++) {
    let resultFAV =
      `<div class="library-favorite-item" li-index="${favoritIt[i].id}" onclick="clickedSingle(this)">
          <div class="library-favorite-data">
            <h1>${favoritIt[i].name}</h1>
            <span>${favoritIt[i].artist}</span>
          </div>
          <audio class="${favoritIt[i].src}" src="songs/${favoritIt[i].src}.mp3"></audio>
         <i class="fa-heart fa-regular"></i>
       </div>`;
    resultsFAV.insertAdjacentHTML("afterbegin", resultFAV);
  }
  favoriteItemsNumber.innerText = $('.library-favorite-item').length;
}

function clickedSingle(element){
  let getLiIndex = element.getAttribute("li-index");
  let i = getLiIndex; i++;
  musicIndex = i;
  loadMusic(musicIndex);
  playMusic();
  playingSong();
  playingSongPersonal()
}

Im getting same divs with same value from li-index="${favoritIt[i].id}". I want to delete if there is a existing same one, or if u can see a mistake that i could made in function above that will help my problem i will be greatfull.

  <div class="library-favorite-info">
    <h1>Polubione Utwory</h1>
    <p>Twoje polubione utwory : <span class="library-favorite-items-number">2</span><br> Zebrane w jedynm miejscu, ku twojej wygodzie.</p>
  </div>

  <div class="library-favorite-container">



  </div>
