Specifically, I'm trying to add my custom enchantment to a loot table with the setup below.

public class AncientCityLootModifier extends LootModifier {
    private final Item addition;

    protected AncientCityLootModifier(LootItemCondition[] conditionsIn, Item addition) {
        super(conditionsIn);
        this.addition = addition;
    }

    @Nonnull
    @Override
    protected @NotNull ObjectArrayList<ItemStack> doApply(ObjectArrayList<ItemStack> generatedLoot, LootContext context) {
        int x = 0;
        int y = 0;
        while(x < 4){
            if(context.getRandom().nextFloat() < 0.08F){
                generatedLoot.add(new ItemStack(ModItems.SCULK_SOUL.get(), 1));
            }
            x += 1;
        }
        if(context.getRandom().nextFloat() < 0.06F){
            generatedLoot.add(new ItemStack(ModItems.SCULK_INGOT.get(), 1));
        }
        while(y < 3){
            if(context.getRandom().nextFloat() < 0.03F){
                generatedLoot.add(new ItemStack(addition, 1));
            }
            y += 1;
        }
        return generatedLoot;
    }

    public static class Serializer extends GlobalLootModifierSerializer<AncientCityLootModifier> {

        @Override
        public AncientCityLootModifier read(ResourceLocation name, JsonObject object,
                                       LootItemCondition[] conditionsIn) {
            Item addition = ForgeRegistries.ITEMS.getValue(
                    new ResourceLocation(GsonHelper.getAsString(object, "addition")));
            return new AncientCityLootModifier(conditionsIn, addition);
        }

        @Override
        public JsonObject write(AncientCityLootModifier instance) {
            JsonObject json = makeConditions(instance.conditions);
            json.addProperty("addition", ForgeRegistries.ITEMS.getKey(instance.addition).toString());
            return json;
        }
    }
}

Deserialize it from JSON and then call its apply method.

Is there an example of how I would do that? I'm not sure how json serialization works, I've just been following this tutorial
