CodeCov is working :)

Regarding Slack, seems there are 2 options from GitHub and Slack.

• https://github.com/marketplace/slack-github (by GitHub, but not in GitHub Actions)
• https://github.com/marketplace/actions/slack-send (by Slack, GitHub Actions)

Have you folks used any of them? Not really sure which one works for us.
