What can be used to implement a simple system for coordinating actions between offices?

Question

System administration

Good afternoon!
I work in a small company with three offices. In the process of work, it is often required to:
1) connect via rdp to a remote server of a partner company;
2) work in the CIAS of another partner (via a browser, web-face), previously logging in with a login-password on the login page.
Both cases are united by the fact that the simultaneous operation of our offices in one system is impossible - each of the partners gave only 1 account, respectively, for normal work, employees need to call each other with the question "do you not work there now? Don't? Well, then I'll come you don't come in."
It is impossible to request a larger number of accounts for organizational reasons.
And now to the heart of the matter:With the help of what tools is it faster and easier to create a system that would display the "busy" status of a particular account?
I could imagine a client-server solution:
- the client monitors the actions on the computer and, when starting an rdp connection to the server / connecting to the site of the second partner, sends a corresponding message to the server;
- the client receives messages from the server and displays the status of the accounts,
However, I have neither the server nor the skills to implement it :)
Maybe something like this could be done in a simpler way? For example, a conference in telegram / jabber / etc, on client computers, a program that tracks user actions and sends messages "% username% logged in to server1" to the general chat on a trigger for this action? Perhaps someone has already encountered something similar, or can suggest simple solutions.

Well, since according to you, the skill is missing, I advise you to contact the freelance exchange.
If you have time and desire to dig yourself, then the easiest option is:
Powershell -> Get-RDUserSession
or take something from the ready ( https://gallery.technet.microsoft.com/scriptcenter...
Get a list of active sessions , well, then you already choose the state through which you will display it. Take some web framework thread, draw a face and throw this data into it. Or take any language practically and write (search on github) API for sending data to telegram / toad or wherever you want.
