Amazon Cognito introduces inbound federation Lambda triggers

The introduction of inbound federation Lambda triggers allows for more flexible and automated handling of federated user attributes, reducing the need for manual interventions and improving reliability in authentication processes.

This update requires changes in IaC configurations to utilize the new Lambda triggers, impacting Terraform, CloudFormation, CDK, and other IaC tools.

This feature enhances our authentication workflows, providing greater control and customization over federated user attributes, which can lead to improved user management and potentially reduce operational toil.
