The inventory function inside the item does not work.

My translation may not be accurate because I'm using a translator.

I have a problem with an item. I wanted right-clicking to open a menu with slots I could place items in. It doesn't work. I created a container in the item's inventory and linked it, but it didn't work. When that didn't work, I created a trigger to open the menu and created a procedure to open the menu with right-clicking. The menu opened, and I could place items in it, but they wouldn't save.

I'm using mcreator 2021.1, mod version 1.12.2.
