Basic Properties

Basic Type (Highly Likely Universal):

    name: "Example Item" # Automatically added to the language
    namespace: "coreextensions" # Namespace
    id: "custom_item" # Item ID
    types: "" # Item type
    maxCount: 64 # Maximum stack size (integer, int type)

This configuration represents a basic item with a name, namespace, ID, item type, and maximum stack size. You can fill in the appropriate values for your specific item.
