Hi there ??
At the moment, there’s no default option to show a popup in WooCommerce after successfully adding a product to the cart, and customizing that would require a bit of additional coding. Custom coding goes beyond the scope of support we are able to provide in this forum.
You may want to take a look at this extension and see if it works for you.
Added to Cart Popup – https://woocommerce.com/products/added-to-cart-popup/
If you want to try it, we have a 30-day refund policy. If the product doesn’t work the way you need or you think another product would work better, we are more than happy to provide a full refund.
You can read more about our refund policy on our website here: https://woocommerce.com/refund-policy/
Alternatively, you can consult a web developer or one of the experts listed at https://woocommerce.com/experts/.
Cheers.
