Hi, how are you? Thank you for helping me out for all of this. I'm finally making some progress and got to the point that I have to query all public journals from all the users on the site. I believe I will have to use custom resolver for this and am not still clear how to set this up.
I just copied over the files you shared here on my project and wanted to see if you can just check really quick.
I assume I will have to edit
Query.getPublicJournals.req.vtlto query all journalsprivacy = PUBLICon the Journal table?
