I need to draw a line between a points current and previous position

CesiumJS
1

Hi
My project updates the position of points from CZML updates sent from a websocket server. This works using the updates and HTML below but I was wondering if it was possible to draw a line between the old and new position of a point. Will I be able to adapt this method to do so or will I need to try something else? Any advice on this or a better way to employ my current method would be helpful.
Thanks
Sam

An Example of the received updates:
[
    {
  "id":"document",
  "name":"foo",
  "version":"1.0"
    },
    {
  "id":"0BE1AD40-7057-4EE0",
  "name":"unnamed",
  "position":{
      "cartographicDegrees":[3.8999858,53.053513,0.0]
  },
  "point":{
      "color":{
    "rgba":[255.0,255.0,255.0,255.0]
  },
  "outlineColor":{
      "rgba":[255.0,0.0,0.0,255.0]
  },
  "outlineWidth":4,
  "pixelSize":20
  }
    }
]

client HTML:

<body>
    <script>
  var viewer = new Cesium.Viewer('cesiumContainer');
  var czmlStream = new Cesium.CzmlDataSource();
  viewer.dataSources.add(czmlStream);
    
  var ws = new WebSocket("ws://localhost:9292/czml-stream");
      
        ws.onmessage = function(update){
  console.log(update.data);
      czmlStream.process(JSON.parse(update.data))
  }
    </script>
</body>

Hello,

You can try to use a path. Here is an example:
