Messages from client A to Client B

I see on the server that it is possible to send messages to a specific client.

Can I do the same from the client ??

I would like to send a message to an other client that it is currently online on the server.

If you open servoy-admin web page from the client you can send a message to all cllents, all clients for a particular solution, or any individual client.

Yes, but what I want, is for my regular users, to be able to send messages to each other. I donM-4t want them to log in to the servoy admin web page.

I want to do this with in the client. By some way to be able to know who is online, and then send them messages.
