Turn on a light to a specific color on any update in GitHub repository

This workflow turns a light red when an update is made to a GitHub repository. By default, updates include pull requests, issues, pushes just to name a few. Prerequisites GitHub credentials. Home Assistant credentials. How it works Triggers off on the On any update in repository node. Uses Home Assistant to turn on a light and then configure the light to turn red.

Help me set up the n8n workflow "Turn on a light to a specific color on any update in GitHub repository" (https://n8n.io/workflows/1856). It uses: Home Assistant. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
