Need help with 3D model image material!

Hi,

I have been wondering how could I set an image material to my 3D model in cesium. Is it even possible?

This is how I add the model:

viewer.entities.add({
  name: "Material change",
  position: Cesium.Cartesian3.fromDegrees(-73.998748, 40.722230, 300),
  model: {
    uri: "./Source/models/example.glb",
    scale: 1,
  },
});
