No. I found this page, but the only schema it provides is the ${recordingId}.zip_metadata.json file.
I need the schema for the ${recordingId}.zip file contents which is the MessageTranscript_${recordingId}.json file.
The .zip file contains a single file MessageTranscript_${recordingId}.json which is not an HTML file, it is a JSON file which contains fields like from, fromContactsContact, to, timestamp, messageId, events, messageText, fromUser.
What are these fields. For example, are to and from fields participant ids?
