Command to open book with json text

[GamingGeek]

Hi, I don't know whether this would be possible with Skript or not but I'm looking to recreate Hypixel's /nick feature. I want to have the command /nick open a book with text and when you click on a rank, it runs a command. I currently have this to open the book but it just says invalid book tag...

command /openBook:
    trigger:
        set {_item} to slot player's current hotbar slot of player
        set slot player's current hotbar slot of player to a written book
        open book player's tool to player
        set slot player's current hotbar slot of player to {_item}

Here is what I'm trying to achieve:

Syntax:

#Expressions:
 
    #Grab a new written book (Because Skript's is different)
    [a] new [written] book
 
#TextComponent stuff
 
    #Create a new text component
    [a] [new] text component [with [text]] %strings%
 
    #Add hover event stuff to the text component (When a player hovers their mouse over it)
    add hover event with action %hovereventaction% (and|with) [(value|text)] %string% to [text component] %textcomponent%
 
    #Add clickable event stuff to the text component (When a player clicks the text)
    add click event with action %clickeventaction% (and|with|to) [(execute|text|link)]  %string% to [text component] %textcomponent%
 
    #Add a page with the text component to a book
    add text component %textcomponent% to [book] %itemstack%
 
    #Message the json text component (tellraw) to the player
    message text component %textcomponent% to %players%
 
    #Works from 1.8-1.12 as tested
