Help/Support Critical Ops

[Shutta IOS 16 S8 LOLLIPOP]

I dont have much knowledge of coding and hacking

c ops have improved their anti cheat , modded apk dosent work anymore because it verifys apk with server when we start game it says invalid application only mod menu works but its paid on autoskillz and i dont wanna buy them

I have downloded a mod menu template and im trying to use it for c ops im pretty sure we need to decompile apk or something please help me out , also i have the idea to steal the modding codes by decompiling and getting source code of modded c ops apk available out there is it possible? 

I am noob i know but if you can guide me little bit how to implement mod menu and cheat codes i can do this

Mod Menu on il2cpp is rare, no idea how ruit achieved that. To steal the modding codes you need access to the paid apk first.
