I have two custom post types: Events (CPT A) and Applications (CPT B), linked using post relations.

I want to create an archive page where the author of an Event can see all Application posts submitted by other users that are related to their Event.
Ideally, the Event author should also be able to edit those Application posts.

I tried filtering by post relation and using the user ID, but it didn’t work.

How can I achieve this in Voxel?
