Con Slack integration is really basic
There is no way to interact with tasks in any way - new tasks can't be added, completed tasks can't be removed, tasks can't be assigned, etc. The integration only sends updates to the Slack channel. There is also no way to fine-tune what updates get posted to Slack.
