How to configure generic S3 storage for flows in prefect.yaml

Hi,

When using prefect init it shows several options for configuring the deployment including S3 with AWS.

But I can’t find any resource in the documentation that shows how to configure the push/pull section of the prefect.yaml file for storing the flow code in a S3 block storage like Minio.

The “pull action” has this pull_from_{cloud} step but what are the possible options?

Can someone point me in the right direction?

Thanks
