How do I implement phone auth using firebase in react native cli?

Initially, I implemented google sign in using Firebase and now I want to implement phone auth in firebase.

Here are the steps, I followed,

1. Enabled the phone sign-in providers.
2. Added SHA certificate fingerprints. and Rest followed the code provided by RN Firebase docs

And I'm getting an error like

Error: [auth/app-not-authorized] This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [ Invalid request fields in play_integrity_token ]

NativeFirebaseError: [auth/app-not-authorized] This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [ Invalid request fields in play_integrity_token ]

How to solve this?
