Cannot Remove Items With Inventory#removeItem()

[Erdo]

Hello

I was making a custom block for my mod and when interacted i want to remove an item and return modified version of it.

If statement for checking item and giving modified item is fine but removing the unmodified item is not working.

Here is the use method of the block :

	@Override
	public InteractionResult use(BlockState state, Level level, BlockPos pos, Player player, InteractionHand hand, BlockHitResult result) {
		 
		 if(player.getInventory().contains(ItemInit.RUBY_ROCKS.get().getDefaultInstance())) {
			 
			 
			
			 player.getInventory().add(ItemInit.EXAMPLE_ITEM.get().getDefaultInstance());
			 player.getInventory().removeItem(ItemInit.RUBY_ROCKS.get().getDefaultInstance());
			 return InteractionResult.SUCCESS;
		 }
		
		 return InteractionResult.FAIL;
		
		
	}
