My app uses custom notifications with custom images. Why do these images get mixed up with those from other apps, causing my notifications to display images from other apps? `INImage *avatarImage = [INImage imageWithImageData:imageData]; NSPersonNameComponents *nameComponents = [[NSPersonNameComponents alloc] init]; nameComponents.nickname = content.title; INPersonHandle *handle = [[INPersonHandle alloc] initWithValue:nil type:INPersonHandleTypeUnknown]; INPerson *messageSender = [[INPerson alloc] initWithPersonHandle:handle nameComponents:nameComponents displayName:content.title image:avatarImage contactIdentifier:nil customIdentifier:customIdentifier isMe:NO suggestionType:(INPersonSuggestionTypeNone)]; INSpeakableString *speakableString = [[INSpeakableString alloc] initWithSpokenPhrase:content.subtitle.length ? content.subtitle : @""]; INSendMessageIntent *intent = [[INSendMessageIntent alloc] initWithRecipients:@[messageSender] outgoingMessageType:(INOutgoingMessageTypeOutgoingMessageText) content:content.body speakableGroupName:speakableString conversationIdentifier:identifier serviceName:nil sender:messageSender attachments:nil]; [intent setImage:avatarImage forParameterNamed:@"speakableGroupName"]; INInteraction *interaction = [[INInteraction alloc]initWithIntent:intent response:nil]; interaction.direction = INInteractionDirectionIncoming; [interaction donateInteractionWithCompletion:nil]; UNNotificationContent *_content = [content contentByUpdatingWithProvider:intent error:nil]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier content:_content trigger:trigger]; [UNUserNotificationCenter.currentNotificationCenter addNotificationRequest:request withCompletionHandler:completionHandler];`
