Trying to log information about event being used

Hello, i am a beginner in C# and i just want to know, how can i log info about an event in-game (CS2)? I have tried to use this https://docs.cssharp.dev/api/CounterStrikeSharp.API.Core.EventPlayerJump.html but when i copy and paste in into my code it doesnt work. I did a basic w3schools exercise on C# and some calculation tasks, so i really dont know much more about anything else in C# :D
