How to use autofill otp like google's one-tap SMS verification with the SMS User Consent API in React Native

Question

I'm trying to achieve phone number verification with the autofill feature in React native application. So far, I've discovered that there are 2 ways i.e either append hash key in sms body or use SMS User Consent API like https://developers.google.com/identity/sms-retriever/user-consent/overview

Is there any way/library through which we can avoid using the hash key?
