Hi Andreas,
This is indeed the place!
I don't use Slack, so I couldn't give this an end-to-end test. But I did spin it up in 5.3 and the server seemed to load it just fine.
I do have one observation: you've named your properties "slack.xxx", which is completely understandable. But the property naming convention would make them "sonar.slack.xxx".
Other than that, it looks good, and I've added it to the
Other Plugins page.
:-)
