how do i make a kills/deaths leaderboard using the roblox weapons kit?

so i have minor knowledge on coding, i already know how to make a leaderboard using simple guns like the slingshot tool for example.

however, i want to use roblox's weapons kit: https://developer.roblox.com/en-us/articles/weapons-kit

the code in these weapons are a lot more complicated, so i'm having a hard time finding where the damage part of the script is. i just need to know where to find it and connect it with a k/d leaderboard script
