First of all thanks for the Feature request and the initial work.

This feature has been on our roadmap for a long time. Now it's implemented and available since version 1.9.0.

@tareksamni Thank you for the well designed notification system for ciao. Maybe we should open source it as a gem?

@brotandgames, Sure we can do that :) If you could start a new repo, I can extract the ruby code, write unitests and implement the CI/CD pipeline.

@tareksamni Sent you an E-Mail to schedule a meeting to discuss this further.
