Hey, I'm on minecraft 1.19.2

I downloaded the mod, but when I follow the wiki and use the demobook it doesn't work. I followed the steps that said I had to add "demobook.xml" in ".minecraft\config\books" and then add "demo.png" under ".minecraft\config\books\resources."

Confusion:

• This command doesnt work "/give @p gbook:guidebook 1 0 {Book:"gbook:xml/demobook.xml"}" but when i use this command "/give @p gbook:guidebook{Book:"gbook:demobook.xml"} 1" i get a book that does nothing when I right click.
• I don't know if I have to include the books.JSON under ".minecraft\config\books" too or not since I'm doing the config method, but even when I tried, it didn't work
• There has to be missing steps
  EDIT: corrected the command

I managed to get a book in that has no cover image (looks at the hotbar at the bottom)
This is what happens when I open it:

Just writing to say I have seen the issue and I keep the tab open, but I'm super busy with work.

I got it to work by downloading someone else's book from a random modpack and working from there, so technically it worked, but i wouldnt have gotten it to work otherwise
