Im asking how to do this Im not 100% sure that its made by this mod, but i somehow made it before. But i forgot how to do it

I think this mod has the feature. It's open source too, so you can check how they do it.

I've finally released this feature in v1.12.0. Drag the image onto the inventory screen (like .nbt files) for a new item, drag onto the new display gui to append to the current lore, and drag onto a book to append to the current page.
