amplify-js: Auth.federatedSignIn returns undefined cred while signin with apple

Describe the bug I use cognito user pool + federeted identity to create unique identities for your users and to securely access other AWS services. I am trying to implement sign in with apple along with normal signin. Normal sign in takes email as username. After following steps mentioned here -https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-social-idp.html , user gets created in cognito user pool but Auth.currentAuthenticatedUser() returns unauthenticated user error. Also cred is undefined.

Auth.federatedSignIn({ provider: "SignInWithApple", }).then(cred => { // If success, you will get the AWS credentials console.warn("success is",cred); return Auth.currentAuthenticatedUser(); })

To Reproduce Steps to reproduce the behavior:

follow these steps https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-social-idp.html

Expected behavior User should get created in user pool as well as federated identity should get created. Auth.federatedSignIn should return valid credentials Auth.currentAuthenticatedUser() should return valid apple user
