List of base class does not draw the inheritance attributes

[RotcivOcnarb]

Have I written this title correctly?

Suppose I have a class Prize, and I want to make a Reorderable List for it.

Now I have different types of Prizes that each has its own class that inherits from Prize, for example CoinPrize, that besides having the original attributes, also have a amount attribute, that I want to also modify in the inspector.

Since obviously you can't add items to the list and expect the class to magically know what type of item you want, I have create separated buttons, each that adds a specific class child for the list

But in the inspector, even if adding the element via the correct button, the child class attributes doesn't show up:

Is there any way I can make this work?

I believe you need to use the new [SerializeReference] attribute on your list.
What happens if you remove the Reorderable list? Does the functionality of adding and drawing different prizes into the list work?
