Answer 1

Here is a documentation on how to use the methods in Class GmailDraft.

A user-created draft message in a user's Gmail account.

To update the draft, try the update(recipient, subject, body) method or update(recipient, subject, body, options) if you have optional arguments.

Also, if you are having problems with the reply, maybe this documentation could help.

There is a sample code on how to create a draft message as a reply to the sender.
