Does anyone have any tips or example configurations for a minimally permissive setup for a Push Pool on AWS? I am referring to https://docs.prefect.io/3.0/deploy/infrastructure-examples/serverless and it lists a lot of required permissions that give the Prefect IAM User essentially blanket access to EC2, ECS, and ECR for our whole account. Ideally, it should just have access to the resources scoped to run the Prefect task.
