Adding more than 4 columns on product page

Add to Home > Settings > Advanced > Code Injection > Header

<style>
  /* products 5 columns */
@media screen and (min-width:992px) {
.products.collection-content-wrapper .list-grid {
    grid-template-columns: repeat(5,minmax(0,1fr)) !important;
}
}
</style>
