Hi everyone, I have just started using metaflow. When trying to run a flow on aws using step-functions, I get this error

when deploying this flow to AWS Step Functions for the first time.
See "Organizing Results" at <https://docs.metaflow.org/> for more information about production tokens.

    Flow failed:
    AWS Step Functions requires --datastore=s3.

I tried searching the docs but didn't find any info about what does this mean? I see only some release notes where it's mentioned.
