CoreData with CloudKit in WidgetKit not working

In my app, I have an NSPersistentCloudKitContainer set up in the following way:

Code Block swift
    let container: NSPersistentCloudKitContainer
    init() {
        self.container = NSPersistentCloudKitContainer(name: "Model")
        self.container.persistentStoreDescriptions[0].setOption(
            true as NSNumber,
            forKey: NSPersistentStoreRemoteChangeNotificationPostOptionKey
        }
        self.container.loadPersistentStores { (_, error) in
            guard error == nil else {
                print("error loading store: \(error.debugDescription)")
                return
            }
        }
        
        self.container.viewContext.automaticallyMergesChangesFromParent = true
    }

When I invoke a fetch request on the context of the container in my iOS target, it works as expected. However, when I perform the same fetch request in my Widget target, it returns an empty array result.

In my iOS target, I have Background Modes / Remote Notifications and iCloud / CloudKit capabilities. In my Widget target, I have the iCloud / CloudKit capability.

Not sure why it isn't working, so any help would be much appreciated, thanks!
