"""
Simple demonstration of the CDP feature.
To test this locally, follow these steps:
1. Create a shortcut for the executable Chrome file.
2. Add the following argument to the shortcut:
- On Windows: `--remote-debugging-port=9222`
3. Open a web browser and navigate to `http://localhost:9222/json/version` to verify that the Remote Debugging Protocol (CDP) is running.
4. Launch this example.
@dev You need to set the `GEMINI_API_KEY` environment variable before proceeding.
