How do I create a document with a Timestamp field?

[timdiacon]

I'm creating a document with a timestamp field using the Timestamp.now() method from the js lib but this results in the field being created as a map in firestore when called from my iOS app? How do I ensure the field is created as a native firebase Timestamp?

import { Timestamp } from "firebase/firestore";

const message: Message = {
    message: value,
    createdAt: Timestamp.now()
  };

  await FirebaseFirestore.addDocument({
    reference: "messages",
    data: message,
  });
