I use the Docusign Java Rest API to create an envelope with one or more documents.
I don’t find the way to send the signed PDF to the signer(s) when the signature process is finished.
Only the account owner get an email with the documents.

                        }
                    ]
                }
            }
        ]
    },
    "status": "sent"
}

Should I use the Carbon Copy parameter or is there another option ? In my opinion, Carbon copy would be for additional people.
