JS AWS Cognito Sign up and link social provider

Question

I need to be able to have a Cognito User Pool user, with the ability to link several different social providers to that user so they can either login using a email/password (basic cognito auth) or via their social account ('email' being the common data field/username).

The flow I currently have:

1) User clicks sign with Facebook, my app handles the oAuth handshake and eventually get the accessToken and email address

2) At this point I couldn't find a way to detect if the user was already registered in the User Pool, so I attempt a Login call with a random password and infer from the error response if the user doesn't exist at all.

3) If the user isn't registered, I redirect the user to registration page so they can provide a Password. Once confirmed, I call SignUp to create a regular cognito user (unverified).

From this point I am stuck.. How do I then associate the Facebook account to this newly created cognito user?

Note: As I'm using custom UI flow for this so using the HoC from aws-amplify-react-native library isn't possible.

Only option is to use hosted ui apart from that there is no doc to integrate social login. — Mohamed Anser Ali, Dec 25 '22 at 21:37

After trying every possible method mentioned in Amplify documentation, it seems social signin with federatedSignin cannot be used with userpool.
