enablePropagateAdditionalUserContextData

When true, your application can include additional UserContextData in authentication requests. This data includes the IP address, and contributes to analysis by threat protection features. For more information about propagation of user context data, see Adding session data to API requests. If you don’t include this parameter, you can't send the source IP address to Amazon Cognito threat protection features. You can only activate EnablePropagateAdditionalUserContextData in an app client that has a client secret.
