[NSFW] carousel-control-next-icon enlarge

Hello,
I have the problem that the next icons (arrows) in the slides are very small. I would like to enlarge the arrows. How can I do that for this slider?

That is the code I have found out with the inspector from Firefox.

.carousel .carousel-control-prev-icon {
    background-image: url(../img/svg/arrow_left.svg);
.carousel .carousel-control-prev-icon, .carousel .carousel-control-next-icon {
    width: 20px;
    height: 20px;
}

the path to which is accessed is: Webpack:///csr/sccs/mbd-free.scss:19

Mann thanks
