I am struggling to understand how to distinguish between a `Cesium3DTileFeature` and an `Entity` that I have created while picking.

In [this](https://sandcastle.cesium.com/#c=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) Sandbox I have added an entity and an OSM tileset.

This is the part of the code where I check for what I am picking

```auto
  if (pickedObject instanceof Cesium.Cesium3DTileFeature) {
    console.log("You picked a Cesium3DTileFeature");
  } else if (pickedObject.primitive) {
    console.log("You picked an entity");
  }

```

and it based on [this](https://community.cesium.com/t/how-to-ignore-the-result-of-3dtiles-only-get-entites-when-i-use-left-click-to-click-on-3dtiles-and-entities/16109/3) answer and [this](https://cesium.com/learn/cesiumjs/ref-doc/Cesium3DTileFeature.html) example from the API docs.

Can you please help me understand what I am doing wrong?

Thanks. I really did not phrase the question that well. Apologies for the confusion.

I am replacing some features from the OSM tileset with entities that have, for example, the correct height. Also, I want to access the same properties of the original OSM feature from the Entity that replaces it.

Entities and features have a different way to set and get properties (AFAIK) so I was trying to identify the type of object picked in order to use the correct method.
