如何在YAML中将S3通知事件发送到Cloudformation中的SNS主题？

如何解决如何在YAML中将S3通知事件发送到Cloudformation中的SNS主题？

我正在尝试在YAML中构建Cloudformation脚本。目的是在S3存储桶（S3BucketTest）中创建文件时，它将向SNS主题（SNSTest）发送通知，该通知随后将消息发送到SQS队列（尚未构建）。我需要帮助的是，在TopicConfiguration部分中，如何为S3通知事件提取主题的ARN？我希望它是动态的而不是硬编码的。我已经尝试过Fn :: GetAtt，但这也不起作用。有什么想法吗？

注意：不要介意格式和全局命名问题。我更改了名称以使其更简单，并且粘贴时格式混乱。谢谢。
