    - Step 2: It listens for an event to start from Google Calendar every 5 minutes.
    - Step 3: Upon detecting a new event, it retrieves the event details, including the event ID and summary.
    - Step 4: The Set CalColor function assigns a color based on the event's colorId, which will be used to set the Slack status emoji.
    - Step 5: The workflow then checks the event's color and routes the flow to the appropriate light control (Busy, Personal, Available).
    - Step 6: It updates the user’s Slack status with the event summary and corresponding emoji.
    - Step 7: Finally, it sends a request to the Philips Hue API to change the light color based on the status determined in the previous step.
