So when I ran chrome audit(lighthouse) it showed me [aria-*] attributes do not have valid values,

it refers to this HTML element

<div class="item-thumb slick-slide slick-current slick-active active" data-owl="0" data-slick-index="0" aria-hidden="false" style="width: 70px;" tabindex="-1" role="option" aria-describedby="slick-slide00">

so I think aria-describedby is not right, from where can I change it to something meaningful value or just remove it as it doesn't make any sense aria-describedby for image slider in the product page.

On searching on the whole codebase I find the file

app/code/MGS/Mpanel/view/frontend/web/js/slick.min.js

But I can't change here as its a library file I guess and everything in one line.

How can I change/remove aria-describedby for gallery vertical thumbnail of the product page
