Hi how https://docs.prefect.io/api/latest/tasks/aws.html actual works? Now our ci/cd pipeline failed when it tried register flows and it did not have proper access to s3 bucket during registration. But then I refactored code to use task which uses boto and ci/cd pipeline passed.

To see how each of those tasks works in detail, you can check the source code, e.g. this one most of those tasks are community contributed so use it when it's helpful and if not, feel free to write your own logic with boto3 for Prefect 2.0, we have Prefect verified collection for AWS tasks here
