Unfortunately, I cannot answer your primary question, but I recommend to update your installation soon, because you are running an unsupported environment.
Unfortunately, I don’t know what you want to do with the large amount of data at the end. But maybe you can activate the Auditing / Logging app. Maybe you’ll find something there. But to see anything at all in the end, you can probably combine it with Grafana Loki, see here. I don’t know if you have a file overview of changes. I do not use it. I see things differently: Whoever is authorised is authorised … I have backups for everything else …
Perhaps it makes sense for you to have several group folders / team folders to which you then assign groups of write users and groups of read-only users in order to better control the write permissions.
