Here is another solution without using JQuery.

I gave the second indicator bar the ID #custom-carousel-indicators.

let carouselIndicatorButtons = document.querySelectorAll('#custom-carousel-indicators button')
document.querySelectorAll('.carousel').forEach((button) => {
    button.addEventListener('slid.bs.carousel', function () {
        let activeIndicator = document.querySelector('.carousel-indicators button.active')

        carouselIndicatorButtons.forEach((button2) => {
            button2.classList.remove('active')
        })

        document.querySelector('#custom-carousel-indicators button[data-bs-slide-to="'
            + activeIndicator.dataset.bsSlideTo + '"]').classList.add('active')
    });
});

I too faced similar kind of issue. So I too used above given solution. But was not working correctly on click. So here is what I did to fix this issue 100%. With little enhancement on above solution.

Issue: I wanted to show 2 indicators for one carousel. Everything works fine after using above solution but fails after clicking.

Solution: So I tried this

$('.carousel').on('slid.bs.carousel', function() {
  var indicatorsAct = $(".carousel-indicator-icons li.active").data("slide-to");
  $(".carousel-indicators-numbers li").removeClass("active");
  $(".carousel-indicators-numbers").find("[data-slide-to='" + indicatorsAct + "']")
    .addClass("active");
});

$('ol.carousel-indicator-icons li').on("click",function(){ 
  $('ol.carousel-indicator-icons li.active').removeClass("active");
  $("ol.carousel-indicators-numbers li.active").removeClass("active");
  $(this).addClass("active");   
  var indicators = $(this).data("slide-to");
  $(".carousel-indicators-numbers").find("[data-slide-to='" + indicators + "']")
    .addClass("active");
});

Where .carousel-indicator-icons is the container class for first indicator and .carousel-indicators-numbers is the class for second indicator.

I hope this will help to other folks who faced similar issue.

I think you need to write some custom js Bootstrap has not this functionality by default so you need to make your own carousel-indicators

css 

.carousel-indicators2 {
  position: absolute;
  top: 10px;
  left: 50%;
  z-index: 15;
  width: 60%;
  padding-left: 0;
  margin-left: -30%;
  text-align: center;
  list-style: none;
}

.carousel-indicators2 li {
  display: inline-block;
  width: 10px;
  height: 10px;
  margin: 1px;
  text-indent: -999px;
  cursor: pointer;
  background-color: #000\9;
  background-color: rgba(0, 0, 0, 0);
  border: 1px solid #fff;
  border-radius: 10px;
}
.carousel-indicators2 .active {
    width: 12px;
    height: 12px;
    margin: 0;
    background-color: #fff;
}

JS

$('.carousel').on('slid.bs.carousel', function() {
  $(".carousel-indicators2 li").removeClass("active");
  indicators = $(".carousel-indicators li.active").data("slide-to");
  a = $(".carousel-indicators2").find("[data-slide-to='" + indicators + "']").addClass("active");
  console.log(indicators);

})

Fiddle
