Dialogflow setup

I have cloud (with alexa skill) configured and Dialogflow talking to the HA dialogflow api. Looking at the setup page for dialog flow “https://www.home-assistant.io/components/dialogflow/” I’m confused by what this section means"When activated, the alexa component will have Home Assistant’s native intent support handle the incoming intents. If you want to run actions based on intents, use the intent_script component." How do I get Alexa to invoke the intent_scripts defined in the example provided on the /components/dialogflow setup page?
