[1.14.4] Rendering thrown item

I asked this exact same question a year back, but between updates and not touching Forge for a while, my old solution doesn't seem to work. I'm trying to create a throwable item in the same vein as the snowball or enderpearl, and everything works except the rendering. Currently, I have a client event subscriber class with the following code

@Mod.EventBusSubscriber(value= Dist.CLIENT, modid = AlchemicalBricksMod.MODID, bus=Mod.EventBusSubscriber.Bus.MOD)
public class ClientEventSubscriber {
    @SubscribeEvent
    public static void registerModels(ModelRegistryEvent event) {
        RenderingRegistry.registerEntityRenderingHandler(ThrownBrickEntity.class, renderManager -> new SpriteRenderer<>(renderManager, Minecraft.getInstance().getItemRenderer()));
    }
}

Botania is open source, and checking that, the method is nearly identical. I don't know if I need to be referencing this class in my main mod class, or what I could be missing.

Any help would be appreciated!
