    ActiveSupport::Deprecation.warn(<<-DEPRECATION.strip_heredoc, caller)
      Providing a String as the model you want to mount is deprecated and will be removed in a future version of
      this gem. Please use the actual model constant instead.

      EXAMPLE

      GraphqlDevise::ResourceLoader.new(User) # instead of GraphqlDevise::ResourceLoader.new('User')

      mount_graphql_devise_for User # instead of mount_graphql_devise_for 'User'
    DEPRECATION
