In Blender go to File->Append. Find the model-> double-click. Open "Collections" folder, then double-click on the name of the Collection and append. To append you can also select the model from another Blender window copying it using ctrl+c and pasting into your scene pressing ctrl+v.
The name of the model and the name of the collection are the same. For use on Eevee, just decrease the bump value on vase material! Displacement is disabled by default but you can turn it on in materials nodes.
Using Simple Asset Manager:
