Please ensure to do as many of the following checks as possible, before asking for committer review:

• DEPENDENCIES are up-to-date. Dash license tool. Committers can open IP issues for restricted libs.
• Copyright and license header are present on all affected files
• If helm chart has been changed, the chart version has been bumped to either next major, minor or patch level (compared to released chart).

Thanks for your quick response! Works great!

As the required parameter is a breaking change, we need to bump the version as a major - app and chart version.

I've sent you a message with a proposal for the admin guide (take care of the links).
