Advanced shulker dupe mod [Minecraft 1.19]

The original mod was made by 0x150 this is just an improvement for the mod to make it more efficient for duping. This is a simple 1.19 mod I made that can dupe an entire shulker box full of items consistently, however, I¬ entirely sure that this is the limit to how many items can be duped with this method, expect a new video soon if it is possible. Does not work in 1.19.1 and above unfortunately.
