For Realm Kotlin sdk, is there a simple way to serialize <https://www.mongodb.com/docs/realm-sdks/kotlin/latest/library-base/-realm%20-kotlin%20-s-d-k/io.realm.kotlin.types/-object-id/index.html|ObjectId>? The ObjectId itself is an interface while the actual object to be serialized is ObjectIdImpl, so I always get the error `ObjectIdImpl is not registered for polymorphic serialization in the scope of ObjectId` when using a custom serializer
