I would expect to find the documentation for

in one these locations 
https://airflow.apache.org/docs/apache-airflow-providers-amazon/stable/operators/index.html

https://airflow.apache.org/docs/apache-airflow-providers-amazon/stable/operators/transfer/index.html


**How to reproduce it**:
<!---

As minimally and precisely as possible. Keep in mind we do not have access to your cluster or dags.

If you are using kubernetes, please attempt to recreate the issue using minikube or kind.

## Install minikube/kind

- Minikube https://minikube.sigs.k8s.io/docs/start/
- Kind https://kind.sigs.k8s.io/docs/user/quick-start/

If this is a UI bug, please provide a screenshot of the bug or a link to a youtube video of the bug in action

You can include images using the .md style of
![alt text](http://url/to/img.png)

To record a screencast, mac users can use QuickTime and then create an unlisted youtube video with the resulting .mov file.
