I'm working on a collaborative editor where multiple people edit the same document. Also, I need to save it in my database with an audit trail. Like

1. who has made what changes to the document?
2. Last changes made by whom etc.
3. If the user is eligible to make edits (if not then throw an error and reject updates)

I'm using the y-partykit library to handle collaboration. But I can't find a way to get the user details whenever an update is coming to the server. What is the best way to achieve this?
