I made a Slack app that publishes a channel to a public URL

In plain words

This Slack app lets users publish a private channel to a public URL, making selected conversations accessible outside Slack. It's designed for teams who want to share channel discussions with people who don't have Slack access. The app transforms internal conversations into publicly viewable content, useful for documentation, transparency, or extending discussion reach beyond workspace members.
