Bug description

It needs to be clarified that if you want icons in v12+ you need 3 things in place.
You need the html as a sibling to .swiper-wrapper

<div class="swiper-wrapper">...</div>
<div class="swiper-button-prev"></div>
<div class="swiper-button-next"></div>

You need the modules config prop

import { Navigation, Pagination } from "swiper/modules";
...
var swiper = new Swiper(".mySwiper", {
      modules: [Navigation, Pagination],
      ...
});

You need the navigation config prop

var swiper = new Swiper(".mySwiper", {
      ...
      navigation: {
        nextEl: ".swiper-button-next",
        prevEl: ".swiper-button-prev",
      },
});

Expected Behavior

Following the documentation while using v12 should produce navigation icons that function.

Actual Behavior

Navigation elements do not get initialized or injected with svg

Swiper version

12.0.3
