ReClass Help

It says in your updating tutorial it says
"Compare each one you find in DNSpy to Reclass, if it isn't 0x0 then its the one you want."
What do i attach ReClass.net to, I thought it might be Rust but if I attempt to attach it will Close my game and tell me
"Security Violation Close Reclass"
I'm not exactly experienced in coding or reversing at all so it could be that but thought I'd ask anyway

If you don't have an undetected Reclass build then just go into a none EAC server and launch the game without EAC by directly opening the rustclient.exe.

I need a video tut on some real shit i haven't got any idea on how to use reclass.net I made my own localhost server with eac off and shit but on your photo the list of stuff didn't show for me it just stayed default
