## Notes

- Empty messages means the user has been timed out. There's no known way to get these.
- This script is using Twitch's API v5 that is [deprecated](https://dev.twitch.tv/docs/v5).
- Consider increasing the delay between API calls in `settings.json` to avoid a potential temporary block from Twitch for sending too many requests when downloading messages from very long streams.
