Hi!
I have installed Onlyoffice on Nextcloud platform. Document functionality works fine, but we have some issues with the anonymous editing. If logged in user edits the file, then i can see who has done the changes. But i can also give shareable links to others which are not registered in our Nextcloud platform. In this case the persona appears as Anonymous when editing the file. Now that 5 anonymous personas are editing document it is hard to track changes and keep track of who did what. I want “not-registered” users to be able to edit the document. In our case, registered users are from our organisation, but non-registered ones are outside our organization. So if we want to share one document with multiple clients for editing, all our clients are marked as anonymous. In that case, i don’t know if client Y or client X did the updates/edits. Because our organization requires paperwork to be done in order to register user in our system, simple solution for me is just ask nickname before editing. + We don’t want to give out accounts to random people so they are able to use our cloud storage 
I contacted the Onlyoffice team already, they told that i should ask for help in Nextcloud community. Maybe there are some solutions for this
