def initialize(session_method)
  super(<<~TEXT)
    Sessions are not enabled. To use `#{session_method}`:

    Configure sessions in your Hanami app, e.g.

      module MyApp
        class App < Hanami::App
          # See Rack::Session::Cookie for options
          config.sessions = :cookie, {**cookie_session_options}
        end
      end

    Or include session support directly in your action class:

      include Hanami::Action::Session
  TEXT
end
