Kill and Death counter

I am making a CS:GO type server. So far everything works it’s FFA and you do /kit to receive kits, but there’s one thing I need and it’s kill/death counters and kill/death ratio. I can’t seem to find any sponge plugin that allows me to do this. Could someone make this or tell me where i can find a plugin? Thanks!

How do you want it? Like a scoreboard on the side of the players screen? Command? Title when X occurs?

I have spent a lot of time trying to find something similar but I have not succeeded.
Ideally, it would work as a complement to the Holograms plugin, to make floating texts with a TOP 5 of users.

Thats a little bit more difficult to what i had in mind but its still easy
