Hello i made a tool that will help map makers and players who play on 1.19.2 and below where the operator items tab in the creative menu haven't been added yet. It is a book with clickable texts that will give you the items you need.

How to use:
Open the book and click on the name of the item you want.

How to obtain:
1.Place down a command block
2.Paste the command bellow into the command block's input
3.Activate the command block with a stone button
4.Test if the book gives you all the items (light blocks are only for 1.19.2 i think)
5.Save it in one of your toolbars or hotbars for ease of use
