This script uses OpenAI's ChatGPT API to create and post a summary of a Slack public channel.

In organizations where the number of channels is increasing, it can be difficult to keep up with reading all the activity. By creating and posting summaries, it is easier to keep track of channel activity.

Most of this code was written using ChatGPT. If you have any better prompts or feature enhancements, please submit a Pull Request.
