Is there any possibility to decrease number of simultaneoursly opened documents?

Hello,
I have realized that PER_DOCUMENT.MAX_CONCURRENCY isn’t limiting our users from concurrent opening the same document. For exampe, I set it to 2, but there were 5 user’s sessions to the single document.

I thought it works by limiting opening any additional user-to-document sessions (which is more than 2).
Is there any other setting that could do that (I set it to 2, so only two documents are available for editing simultaneously)?

Concurrency there means the number of threads you can use at once as the comment says: “The maximum number of threads to use while processing a document.” - and does not limit the number of users who can edit a document - or the number of simultaneously opened documents. I’m curious why you’d want that. There are compiled-in limits on the max. number of open connections and documents - that can be configured if you so desire, but would be good to grok your use-case.
