How to trace a message from a large number of dialogs using socket.io?

• 0
  Hello! I want to implement a chat page for my application. The logic will be as follows: when a user goes to the chat page, all his dialogs are displayed to him. After all dialogs are displayed by dialogId, I connect them all in sockets. My question is:
  how can I catch a message if someone writes me from my dialogues?
  
  1) I get the Id of all dialogs
  2) By these Id I connect to the rooms.
  3) How can I track if someone writes me a message from any of these dialogs?
  Frontend
  

  useEffect(() => {
      const dialogsId = dialogList.map(value => value.dialogId)
     	socket.emit('joinDialogs',  dialogsId);
    }, [dialogList]);

  
  Backend
  

  socket.on('joinDialogs', (dialogsId) => {
      socket.join(dialogsId);
    });
