问题
There's new feature in aws cognito to allow user to sign in through external federation identity providers in user pool. I followed the steps given the aws Doc. 1) select identity providers 2) attributes mapping But when I sign up, fb/ Google account ID don't get map in user pool. Can someone give me a proper code to do this. I mean how should I map fb/ Google user sign in programmatically in cognito user pool.

Currently, only the Facebook id, Google sub, and Login with Amazon user_id attributes can be mapped to the Amazon Cognito user pools username attribute.
What does your attribute mapping look like?
