AWS S3 bucket duplication/ sync inside node application

Things work fine in the aws command line using : aws s3 sync s3://firstbucket s3://secondbucket.

My goal is to spin up a new bucket and get all the files from a fixed bucket(s3 -> s3), inside a node app. I didn't find any functions I can use on the Official API document. some of the packages can only handle local -> s3 and s3 -> local.

Please Help!
