aws-cloudformation - 无服务器框架 - 配置 Cognito 用户池以通过 SES 发送电子邮件

Question

我能够使用无服务器框架创建 Cognito 用户池。不幸的是，新用户注册后的电子邮件验证是使用 Cognito 的电子邮件传送系统发送的，该系统非常有限。我知道我可以进入控制台并更改选项以使用 Amazon 的 SES，但如何在无服务器框架中执行此操作？

使用用户池中的EmailConfiguration 属性。

UserPool:
    Type: AWS::Cognito::UserPool
        DeletionPolicy: Retain
        Properties:
            ...
            EmailConfiguration: 
                EmailSendingAccount: DEVELOPER
                ReplyToEmailAddress: # email address
                SourceArn: # sourceARN to verified email address in SES
