QB-Target being used on an ESX Server

I am trying to use this script on my ESX server https://www.youtube.com/watch?v=T1mPZCmKhVs&ab_channel=MJDEVELOPMENT I used to play on a server that was ESX and this script was used on it, I am wondering how to install it because the basic install method is not working for it. I am not sure if this is the exact same targeting script as the one that the server I used to play had, but the look of it is the exact same as it. I have clips of the server having this targeting system and I am sure that it was not QB-Core. Please someone help me out.
