@Andreas_Hegenberg The Finder Recents functionality is very limited. Even basic file/folder creations, rename, deleted are not supported. Not to start about previewed files or folders(not even avail in MacOS). For deleted items you can check the trashcan, but a link between Recents and trashcan sounds reasonable to me. Unless it's been emptied of course. Maybe BTT can provide a more advanced polished Recents.
I've been using fswatch but its not end-user friendly.
