Multiplayer to perform interaction on one model from 2 users

Questions
1

Is there an example of using multiplayer in babylonjs?
My aim is to create the two given steps:
(a) Create a room with user-name and other users enter the room
(b) One cube is present in the room and all users can rotate its ArcRotateCam. This should be reflected on all the users screen

I am using example from here : Share 3D Models with WebSockets Demo | by Babylon.js | Medium where socket.io is used with express for multiplayer.

How do I proceed with this?

Wow what a huge question. To begin with I suggest you search for ‘multiplayer game’ in this forum

In the old forum this is a useful post

I followed the forum link that I had posted and set up a scene where the model gets uploaded well and is broadcasted in all the client’s scenes. Now I would like to update the rotation of camera in all the scenes. For example, if client 1 rotates the camera then client 2 should get the rotated camera’s transforms and apply it to its camera. How do I do this?

index.html

var camera = new BABYLON.FreeCamera('camera1', new BABYLON.Vector3(0, 5, -10), scene);

//more code

scene.onBeforeRenderObservable.add(() => { //Gets called each frame
        socket.emit('modelRotate');
        updateModel(scene);
      })

socket.on('modelRotate', function () {
        updateModel(scene);
      });

function updateModel(scene) {
      camera.node.rotation = new BABYLON.Vector3(camera.node.rotation.x, camera.node.rotation.y, camera.node.rotation.z);

    }

index.js

//More code

  socket.on('modelRotate', () => {
    socket.broadcast.emit('modelRotate');
  });
