Display in iOS app (webview) and in-app purchase

Good afternoon,

I searched a lot of documentation but couldn’t find the answer. Is there documentation on the integration of the wordpress->woocommerce website loaded in the iOS application via webview and paying for the digital service directly in the application (in-app purchase)?
The App Store will not approve an app without an in-app payment option.

“How can I add custom code to each ‘buy’ button of my product that will fire when the user clicks on it?” I am hosting my website in a webview app and want to check the host browser and then (A) if the browser is my webview app = load a specific url to trigger native in-app purchases or (B) if the browser is any other browser = use the woocommerce purchase flow .”

Thank you so much for all the support
