What is the latest and working method or script to view real IP of a site behind Cloudflare

Please who can help me with the working script to view real IP of a site using Cloudflare, all the script I got from GitHub doesn’t work any longer

Hi,
Did you try Behindflare?

https://pkg.go.dev/github.com/alebeta90/behindflare#section-readme

Or Shodan maybe?
