Do I need to instantiate multiplayer assets?

Do I need to instantiate a prefab in order for it to be seen on the server?

Example is that I have a scene with a prefab with a network view and I want other players to see it, must it be instantiated? or can it just be present in the scene?

am super new to multiplayer code:

Thanks guys!

It does not have to be instantiated. It can just be presented on the scene.
