Basic Help with Node-RED and Alexa commands

I am new to this, and trying to do something basic.
I want to tell Alexa to turn a light on…
I can’t find any examples of how to do this on the node-red sites.

This is where I am now.
I have Node-red installed in Home Assistant
There is a few Node-RED Alexa sites that have the service to access to Alexa.
I signed up on both of them and created the light “device”
I can see the light in Alexa, and the voice command works.

What I am missing is how to setup the code-RED coding to make it work.
Is there a site or something that shows the basic method to do this?
