How to install IF snippet on MODX Revolution 2.4.2-pl?

Question

MODX

Always worked on MODx Evo. Recently a friend asked me to help him with his website. Site on MODX Revo. Everything is very similar to the Evo. You need to use the IF snippet. But there was a problem: IF snippets are different there. I would have dealt with this, but here another problem arose: I can not find the Internet, and download the if snippet for MODx Revo. I am relatively new in this profession. Tell me how to install this snippet on Revo? Or is it built in? I used to find the snippet code, copy it, create a new snippet in my MODx, name it properly, and paste the code.
