`require` in Elixir is not like `require` in your prior language. That quote you included from @mgwidmann explains it well. `require` is about macros, and you’re not using macros.

Edit to add:  
The getting started guide is a good place to … well .. get started. It covers `require` in more depth here: [https://elixir-lang.org/getting-started/alias-require-and-import.html#require](https://elixir-lang.org/getting-started/alias-require-and-import.html#require)
