'Python chat server with selectable specific user to chat

I am trying to write simple chat based desktop support app. The gui is not problem, but I have problem with sending messages. The server sends it to all connected clients, but I want request and response to be private between server (or admin) and specific user. I have tried sockets and twisted, but can't figure out how to choose client to contact with.

So if there is any project like what I am trying to achieve on python 3 link or comment for reference. This is my school project for school local network.

Thanx in advance.
