We use gerrit as our SCM and I'm configuring tests in jenkins to have -+1 opinion on our code reviews. I have configured multibranch pipeline according documentation. I can see branches in the branch view but no jobs are triggering. I have gerrit trigger plugin which works on the server. The documentation says that "configure gerrit trigger as normal" but there is no option to configure it in multibranch pipeline options. I can neither modify any options in any of the pipelines in multibranch.

How do I "configure gerrit trigger as normal" when there are no options to configure it?
