However, if you do it by using CDK, it can be a lot simpler because CDK will help us take care of creating CF custom resources to handle circular reference if need automatically. The stack in which this resource is defined. The next step is to define the target, in this case is AWS Lambda function. I've added a custom policy that might need to be restricted further. The expiration time must also be later than the transition time. Subscribes a destination to receive notifications when an object is created in the bucket.
