Presentation-specific chat: 4 tab Logic taken into account

Until now, all people within a presentation who had access to this presentation could chat in Leanr – regardless of their role for this presentation.

We have abandoned this idea and have now logically used the 4 tabs in the presentation editor for chat purposes as well. Users will no longer be able to chat at all – only reviewers (and managers) in the review tab, and editors (and managers) in the draft tab. This channels all communication in a targeted manner.
