In Jira it is possible to store properties for users following this endpoint, which then it is possible as well to retrieve using Automation Rules with smart values with the syntax {{user.properties.propertyname}} as shared here.
I was able to use an external tool to store a user property in Confluence, using this endpoint, but it seems it is not possible to retrieve user entity properties using Smart Values, even though trying with the same syntax.
Would anyone be able to confirm or deny this?
Thanks a lot in advance.
