Creating a new GameObject by code without an inspector prefab

Unity Engine
1

So In this game the player can find chests, these chests can have, at ramdom, one of ten different items.

So when the player opens a chest this happens:

// Mockup code
[SerializeField] GameObject[] items;

void OpenChest() 
{
  int index = Random.Range(0, items.Lenght);

  Instantiate(items[index]);
}

The problem with this solution is that I need to drag the 10 items (gameobjects) to the chest’s script, and that’s for every chest in the game. It seems like a waste of resources. Is there a way to Instantiate or create an gameobject on the fly, without having an instance in the inspector. For example:

int index = Random.Range(0, items.Lenght);

switch(index)
{
 case 0: Create(BlueCoin); break;
 case 1: Create(Sword); break;
...
}

You can use Resource.Load() to get a prefab by name. You could also use something like a scriptable object that holds all the prefabs and links them to, for example, an index.
