Double check you have configured all the “scopes” listed in the plugin topic: [Set up Slack notifications using the discourse-chat-integration plugin](https://meta.discourse.org/t/set-up-slack-notifications-using-the-discourse-chat-integration-plugin/66730)

Do slash commands work from the private channel? If so, try creating a rule using those, and see whether it appears in the Discourse admin interface.
