Increase space between products shop page (MOBILE ONLY)

Site URL: https://www.amovintage.com/

Hello

Please can someone help me increase the space between products on my shop page? I cannot work it out or find a code anywhere, happy with it on web view but concerned that most views are by web so want to change mobile view exclusively if possible just to make it look a bit more spaced out / less squished in

Have attached website link and some photos underneath

Thanks so much!

Hi. Add to Design > Custom CSS

/* Products space */
@media screen and (max-width:767px) {
.products.collection-content-wrapper .grid-item.is-loaded {
    margin-bottom: 70px;
}
}
