You can add image background for your menu using this code

#Details-HeaderMenu-1 #HeaderMenu-pokemon > span {
    background-image: url(https://cdn.shopify.com/s/files/1/0028/9852/6243/files/Screenshot_1.jpg?v=1702101181);
    background-position: center;
    background-size: cover;
    color: transparent;
}
