I can't find i way to remove(consume) an item after onItemRightClick... help please?

I tried doing

@Override
	public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) {
		playerIn.heal(1.0f);
		return ActionResult.resultConsume(playerIn.getHeldItem(handIn));
	}

but it still doesn't do anything.

ItemStack.shrink()

This can be found easily in other places like food, bow, etc... please have a look at them.

I think you have to manually shrink the ItemStack also.
