Insert tree models in CesiumIon

Hi all, I am quite new to Cesium, it seems that cesium Ion did not allow user to use the same asset twice in a story, in my case I need to place multiple tree models inside my story, how can I achieve that? Thanks

CesiumJS supports mesh instancing. You can use a GeometryInstance to render multiple instances of your trees in different locations. If the tree models are unique and you’re encountering an error uploading multiple different tree models could you please provide the asset IDs for the ion failures so we can investigate? Thanks.
