3DTileset from Cesium Ion appears only when the camera is too close to it

Hi, I have uploaded a model to cesium ion, the asset id is 305173.

The code to load it :

var tileset = viewer.scene.primitives.add(
  new Cesium.Cesium3DTileset({
    url: Cesium.IonResource.fromAssetId(305173),
    skipLevelOfDetail: true,
  })
);

tileset.style = new Cesium.Cesium3DTileStyle(
{
  show : "${Height} > 0",
});
viewer.trackedEntity = tileset;
viewer.flyTo(tileset);

The model appears but only when I am too close with the camera.

How can I make it perpetually visible?
