You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: finder_with_find_by.rb
    path of file: ./repos/gitlabhq/rubocop/cop/gitlab
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RuboCop
  mo
    
        def message(used_method)
          <<~MSG
          Don't chain finders `#execute` method with `##{used_method}`.
          Instead include `FinderMethods` in the Finder and call `##{used_method}`
          directly on the finder instance.

          This will make sure all authorization checks are performed on the resource.
