.WithNotifications() signature broke after GQL

[stefano-ottolenghi]

There seems to be a bug in notifications filtering. The GQL overloading of .WithNotifications() broke its intended signature. As API docs read, I should be able to call .WithNotifications(Severity.Warning, null), but that fails with
