How can I find the Header Message-ID

The provider changes the Message-ID when they send it, after we deliver the message to the provider.

1. Create draft
2. Send - returns Nylasmessage_id
3. Wait formessage.updatedfor thatmessage_id
4. GET the RAW /message
5. This will return the sent message object with the updatedMessage-ID

Please note this can take up to 10 minutes to update.
