@mtojek Did you add the kibana review manually? We've excluded the folders with the actual tutorials from the code ownership to make it possible for teams to merge in tutorials without going through the "Kibana app" review gates (mainly because we don't know much about the data sources added and whether everything is accurate).

So feel free to have this approved by someone at your team, no need to block on us. If this is to get a mandatory second pair of eyes on the change, we are happy to verify.

Thanks, unmarking "kibana-app" and will reach out to beats team members.
