Scaling a 3D tileset in CZML packet

3D Tiles
1

Hello, I am trying to load a 3D tileset via CZML file. While I am able to load the tileset to desired position and orientation via CZML properties, but Scale property does not seem to be working.

I have tried adding ‘scale’ property to the tileset packet by providing Cartesian3 values as described here, but it does not take effect.
Here is my CZML packet :

{
    id: "ContainerCafe",
    name: "ContainerCafe",
        
    position: {
      cartographicDegrees: [
        76.6065220915297,
        28.197797154942055,
        -1.2419161288437142
      ]
    },
    
    tileset: {
      uri:
        "http://localhost:3000/assets/tileset.json",
    },
    
    scale: {
      cartesian: [100.0, 200.0, 300.0]
    },

  }

Any assistance / insights would be highly appreciated.
Thanking you!
