Rails Active Storage and Acts as List

Question

I've been working on a way to add acts_as_list to ActiveStorage::Attachment using a concern. I've been working on this for two days and can't seem to find a way to add the line acts_as_list to the model. I tried to load with an initializer. Any thoughts?

Here's the initializer code:

Rails.configuration.to_prepare do
  class ActiveStorage::Attachment
     include ActiveStorageActsAsList
  end
end

Concern

module ActiveStorageActsAsList
  extend ActiveSupport::Concern

  included do
    acts_as_list
  end
end
