In my scenario a user can join multiple room. Can I understand from which room the user is sending a message on the server? In the example below, I am sending the ID of the room the user is sending the message to in the package.

Client Side

  ...
    const SendMessage=()=>{
      // Get active room id
      const selectedRoomId = document.getElementById("channelList").value;
      socket.emit('srv-chat-message', 
      { 
        'roomId':selectedRoomId, 
        'message':'Hello world' 
      });
    }
 ...

Server Side

 ...
 socket.on('srv-chat-message', (data) => {     
    io.to(data.roomId).emit('cln-chat-message', {
      message: 'Hello from server'
    }); 
 });
 ...
