Ratchet. How to implement correspondence between two registered users using Ratchet?

Question

JavaScript

How to implement correspondence between two registered users using Ratchet (and it is desirable to do this safely, otherwise I have one option, but this is more likely not a solution, but an unsafe crutch). The documentation has an example of how to implement correspondence between all users (or rather, chat participants), but I could not find something how to implement between 2 specific users.

There are various chats with rooms, maybe the solution would be to implement a separate room for each pair of enumerators (a separate channel for correspondence). But I didn’t find how to do this either ((

How can I understand which registered user in YII2 is a chat participant?
How can I match them by id?
