How to integrate google pay in xamarin for application for iOS?

Question

I am creating a demo project in Xamarin and in that, I want to use google pay(gPay) as a payment option. I have checked many sites/videos on the internet and it is providing solutions for android implementation but none of them have iOS implementation. From android, I have got that this payment with google-pay will be done with the deep-linking and it needs to be implemented in the native structure of the project for making it work or open other applications and get a response from the payment app after the payment process completion. Can you please help me with this?

Thanks.
