How to manage client connections using GNAT.sockets?

This is a chat client / server program. To make a broadcast, I have to save each client that connects, and then write to each of them, right? What is the best practice for customer management?

    GNAT.Sockets.Accept_Socket(
         Server  => Receiver,
         Socket => Connection,
        Address => Client
    );
    Channel := GNAT.Sockets.Stream(Connection);
    String'Write(Channel, "Welcome Message");
