How do I determine if Hotwire is enabled in upgraded app?

The Rails app I am working on was recently upgraded from Rails 6 to Rails 7. What is the most straightforward way to determine if all of the Hotwire goodness (gems, ActionCable, etc.) is enabled in this upgraded app?

After generating a new Rails 7 app via rails new and comparing its Gemfile/Gemfile.lock with that from my upgraded project, it looks like I need to include the following:

# Hotwire's SPA-like page accelerator []
gem "turbo-rails"

# Hotwire's modest JavaScript framework []
gem "stimulus-rails"

ActionCable and redis are already included in my upgraded project. And ActionCable is configured via config/cable.yml to use the redis adapter.

Is there anything else I should check?

I think there might be an install scrip you will need to run. Those are described in the Installation section of the readme here: GitHub - hotwired/turbo-rails: Use Turbo in your Ruby on Rails app

Same thing for stimulus: GitHub - hotwired/stimulus-rails: Use Stimulus in your Ruby on Rails app
