更改引导程序轮播指示器

Question

我使用了 bootstrap 5 carousel。我想将指示器图标更改为圆形。

            <div class="carousel-indicators">
              <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
              <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="1" aria-label="Slide 2"></button>
              <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="2" aria-label="Slide 3"></button>
            </div>

如何改变这一点
