How to upgrade the Slack app to enable Challenges
With the release of the Challenges feature on March 7th 2022 you need to upgrade the Slack App.
This upgrade will allow the app to post to public channels without having to be explicitly added as an integration.
The upgrade is very simple and doesn't affect anything on your side. And of course it doesn't cost anything extra. ☺️
1. Click the button in the App Home tab
2. Click the "Add to Slack" button
3. Add it to the same workspace that you had before
