Trying to Share a Record, "Only shared zones can be accessed..."

I'm struggling to share a record. I'm getting and error that my zone is not shared. No idea how to share the zone either than doing the process below. Error is here...

Code Block 
<CKError 0x28107db30: "Partial Failure" (2/1011); "Failed to modify some records"; uuid = 025CA822-96A0-46FB-B2EE-7CB06D1ECCF8; container ID = "iCloud.[MY DOMAIN]"; partial errors: {
	Share-182263AB-B5AC-466D-A5D0-34F63D37ADDA:(GameZone:defaultOwner) = <CKError 0x281077bd0: "Invalid Arguments" (12/2006); server message = "Only shared zones can be accessed in the shared DB"; uuid = 025CA822-96A0-46FB-B2EE-7CB06D1ECCF8>

I created a custom zone using the following...

Code Block 
	CKContainer *container = [CKContainer defaultContainer];
	CKDatabase *db = container.privateCloudDatabase;
	CKRecordZone *tempZone = [[CKRecordZone alloc] initWithZoneName:@"GameZone"];
	[db saveRecordZone:tempZone completionHandler:^(CKRecordZone * _Nullable zone, NSError * _Nullable error) {
		if (error != nil)
		{
			NSLog(@"%@", error);
		}
		else
		{
			NSLog(@"Successfully created GameZone --- %@", zone);
		}
	}];

I then saved a Record using this zone. I've confirmed that the record exists, in that zone, in my private Database on the dashboard.

I then initiate the share (using the UICloudSharingController) as follows...

Code Block 
	Game *theGame = [self.common.coreManager getGameByObjectID:self.gameObjectID];
	CKRecord *record = [[CKRecord alloc] initWithRecordType:@"Game" recordID:theGame.ckID];
	
	UICloudSharingController *sharingController = [[UICloudSharingController alloc] initWithPreparationHandler:^(UICloudSharingController * _Nonnull controller, void (^ _Nonnull preparationCompletionHandler)(CKShare * _Nullable, CKContainer * _Nullable, NSError * _Nullable)) {
		[CloudKitManager shareRootRecord:record name:theGame.name completion:preparationCompletionHandler];
	}];
	[sharingController setModalPresentationStyle:UIModalPresentationFullScreen];
	[self presentViewController:sharingController animated:YES completion:nil];

Finally my CloudKitManager shareRootRecord looks like this...

Code Block 
+ (void)shareRootRecord:(CKRecord *)rootRecord name:(NSString *)name completion:(void (^)(CKShare * _Nullable share, CKContainer * _Nullable container, NSError * _Nullable error))completion
{
    CKShare *shareRecord = [[CKShare alloc] initWithRootRecord:rootRecord];
    shareRecord[CKShareTitleKey] = name;
	shareRecord[CKShareTypeKey] = @"com.lmw.YouDJ";
	[shareRecord setPublicPermission:CKShareParticipantPermissionReadOnly];
    NSArray *recordsToSave = @[rootRecord, shareRecord];
    CKContainer *container = [CKContainer defaultContainer];
    CKDatabase *privateDatabase = [container sharedCloudDatabase];
    CKModifyRecordsOperation *operation = [[CKModifyRecordsOperation alloc] initWithRecordsToSave:recordsToSave recordIDsToDelete:@[]];
    [operation setModifyRecordsCompletionBlock:^(NSArray<CKRecord *> * _Nullable savedRecords, NSArray<CKRecordID *> * _Nullable deletedRecordIDs, NSError * _Nullable error) {
		if (error)
		{
            NSLog(@"%@", error);
        }
        completion(shareRecord, container, error);
    }];
    [privateDatabase addOperation:operation];
}

Line 19 is the output of this error. I'm confused what to do here. I though the act of sharing out this record in this custom zone should make that zone shared? I'm not sure what else I'm supposed to do on the custom zone? I can't find anything in the Documentation or even online about how to share the custom zone either than just sharing the record.

Very much appreciate any suggestions here.
