How to pull twitter followers

Looking to be able to pull new twitter followers into a google sheet, I know I can’t use the regular twitter API and I need to make an HTTP request but can’t find and guide or documentation on how to achieve this, if anyone could hold my hand or point me in the right direction I would be very thankful.

my request is similar to this - Add new Twitter followers as CRM contacts

I know I must use this but I can’t figure out how - GET friends/list | Docs | Twitter Developer Platform

I really dig this project and if I can figure this out I’ll be happy to show others!
