CloudFormation added support for UsernameAttributes
As pointed out here - https://github.com/AnomalyInnovations/serverless-stack-com/pull/239; CloudFormation now supports this attribute. This means that we don't need to use the email as alias workaround on the frontend. We can also test our APIs using the email as the username.
We'll be rolling out this change to the tutorial, backend and frontend repos shortly.
The changes are in this branch - https://github.com/AnomalyInnovations/serverless-stack-com/tree/usernameattribute.

Released the new version - https://github.com/AnomalyInnovations/serverless-stack-com/releases/tag/v3.1
