How do you monitor GitHub Workflows?

If you have a number of GitHub Workflows to carry out tasks such as running integration tests, how do you keep track of them?

1. Just watch out for any failed emails?
2. Set up to get a Slack notification?
3. Anything else innovative I haven't thought of...?

I've been using a combination of 1 + 2, which is unmanageable after a while, especially when overwhelmed by Slack notifications while trial-running the workflows during their own development.

I wondered if anyone has found any good ways to keep an eye on workflow runs without being disturbed too often (but without missing important failures!).
