I'm currently using the Storefront API to build an e-commerce based on a web-app (Next.js, so React).
To make a payment, I get the `webUrl` field with a graphQL mutation.
My purchase module is Vivawallet. When I close the purchase, I don't have a return button.
Ideally, I would like to be able to create a `returned_url` to 'www.my-shop.com/return-checkout/...'
Please note that the site is not hosted on Shopify but via an external server. So I don't want a return to 'my-shop.myshopify.com/...'.
Thanks to you !
