Restrict editors to a particular language in the panel

I’ve seen that this has been asked about before here in the forum, but non of the pages leads to a successful answer. (no answer / no answer / can’t get it to work for what I need )

So I’m asking again:
Is there a way to restrict an editor to a specific language in Kirby 3.5.1 ?
We are in the process of translating a website into 8 languages, more might follow.
It would be extremely helpful to restrict the access of every editor to their assigned language.

If an admin will have to create the pages first, would be fine.

As far as I know, this is currently not really possible, or at least I’m not aware of an easy way to achieve this.
