Update Amplify

Amazon Cognito does support Identity Federation out of the box with Login With Amazon, Login with Google, Login with Facebook, Signin with Apple, or any OIDC or SAMLv2 compliant identity provider.

We use AWS Amplify command line to update the Amazon Cognito configuration on the backend and add support for Login With Facebook.

It is important to not overwrite the values we entered previously, be sure to follow instructions carefully.

In a terminal, type:
