How can I add navigation arrows to a coverflow slider?

[alivault]

I have a slider here that has a coverflow effect. I have the swiper-button-prev and next elements in there plus navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
in the script. What am I doing wrong?

You are not importing navigation styles. Everything fine with JS and config.
You probably importing only core styles swiper.scss.

SCSS Styles
SCSS styles are also separate styles for core version and components:

swiper.scss - only core Swiper styles
components/a11y/a11y.scss - styles required for A11y component
components/controller/controller.scss - styles required for A11y component
components/effect-coverflow/effect-coverflow.scss - styles required for Coveflow Effect component
components/effect-cube/effect-cube.scss - styles required for Cube Effect component
components/effect-fade/effect-fade.scss - styles required for Fade Effect component
components/effect-flip/effect-flip.scss - styles required for Flip Effect component
components/lazy/lazy.scss - styles required for Lazy component
components/navigation/navigation.scss - styles required for Navigation component
components/pagination/pagination.scss - styles required for Pagination component
components/scrollbar/scrollbar.scss - styles required for Scrollbar component
components/thumbs/thumbs.scss - styles required for Thumbs component
components/zoom/zoom.scss - styles required for Zoom component
