Install fontawsome on Rails 7.0.4.3

How can I install fontawsome for icons on Rails 7.0.4.3 and ruby 3.2.1

I tried three methods:

1. yarn add @fortawesome/fontawesome-free + import "@fortawesome/fontawesome-free/js/all"
2. ./bin/importmap pin @fortawesome/fontawesome-free + import "@fortawesome/fontawesome-free"
3. gem "font-awesome-sass", "~> 6.3.0" +  bundle install + @import "font-awesome"

But when I test with an icon it is not rendering.
