Comala Workflows - using pageapproved to send email

[Susanne_ERTLE]

Hello community, I am rather new to Confluence and Comala and hoping you can help me. I have created a new workflow for us and in general it now works quite well apart from one problem.
I have a state called "In Review" which has two approvals: Content Review and Quality Review. I am currently informing my users via email (trigger:pageapprovalassigned) that they have been assigned as reviewers. But, as the Quality Review can only start once the Content Review has finished, this isn't very practical. I want to inform my quality reviewers when the content review is finished. I have found the parameter "pageapproved", which is supposed to work the same way as "pageapprovalassigned", at least that's what I understood. But - it doesn't work, the email never gets sent. What am I doing wrong?

{trigger:pageapprovalassigned|approval=Content Review}
{send-email:user=@Content Review > approvalassignees@|subject=Page content review assignment}
