使用 cognito 時，通常會想要客制化寄信出來的 message
目前的作法
- 因為需要在寄出來的信件中，顯示相關的 customer attribute，目前找到 & 使用的方式為 trigger lambda 的方式
- 修改 trigger 為 “Custom message”
aws cognito-idp update-user-pool --user-pool-id $POOL_ID --lambda-config CustomMessage="arn:aws:lambda:us-west-2:xxxTest"
- Custom message Lambda trigger - Amazon Cognito

- spring - Cognito Customise Messages and Include User Attributes - Stack Overflow AWS console 介面中的 Message customizations Tab 無法設定使用 customer attribute
