Hi! I would like to change the "add to card" button on product pages to a customized image. Is it possible to do via the custom CSS editor?

Add to Design > Custom CSS

div.sqs-add-to-cart-button {
    background-image: url(https://cdn.pixabay.com/photo/2022/07/01/14/29/wheat-7295718__340.jpg);
    background-size: cover;
    background-repeat: no-repeat;
    background-position: center center;
}
