Apple Account Balance Payment Option

I’d love to see an option to pay for Venice subscriptions or credits using my Apple Account balance, like a normal App Store in-app purchase.

Right now, purchasing through the iOS app takes me to the website, where I can only pay with a credit card. I have money in my Apple Account balance that I’d like to use instead.

Would it be possible to offer Apple’s in-app purchase system for subscriptions or credits? I think this would be a really convenient option for iPhone users who prefer to pay through Apple.

Thank you!
