.setDocumentDetectorFlow(flow :[DocumentDetectorStep])
Sets the document capture flow, as explained here​
Yes
.setPeopleId(peopleId: String?)
Identifier of the user for the purpose of identifying a fraudulent profile

​
let documentDetectorConfiguration = DocumentDetectorBuilder(apiToken: "API_TOKEN")
    .setDocumentDetectorFlow(flow: DocumentDetectorBuilder.RG_FLOW)
    .setLayout(layout: layout)
    .build()
