so basically, how do I make the grant menu loop all of the ranks and variables for its correct variables?

Currently, it's hardcoded for:

Owner rank:
&4&l%player's displayname% (for like muting the chat or switching worlds or staff chat)
&4&lOwner (for the formatted rank setting)

Co-Owner
Developer
Manager
Head-Admin
Sr-Admin
Administrator
Head-Mod
Sr-Mod
Moderator
Head-Builder
Sr-Builder
Builder
Trainee
Default

(I want to make it for VIP or MVP)

Plugins used that are worth noting:
Skript
Luck Perms
Vault

Addons:
Eratz 1.0
SkQuery 3.6.0 Lime
skRayFall v1.9.18
TuSKe v1.8.2

I want to make the grant menu list all of the ranks in Luck Perms (as well as work & be valid in setrank)
this is honestly very hard, but my 'friend' Preceding made a skript permissions plugin completely in skript (with addons and vault ofc)
