Provide custom spawn data when spawning via MultiplayerService

[NotBjoggisAtAll]

Hi,

I just wonder if its possible to provide custom spawn data when spawning via the multiplayer service?

Now my client crashes when spawning my entity, because spawn data is not provided.

Example code below

// Called on server
Entity entity = spawn("card", new CardSpawnData(x, y, card.suit(), card.rank()));
getMultiplayerService().spawn(connection, entity, "card");

----
// Spawn method
  @Spawns("card")
  public Entity newCard(SpawnData data) {
    if (!(data instanceof CardSpawnData cardSpawnData)) {
      throw new IllegalArgumentException("CardSpawnData required");
    }
    ...
  }
 
----
// Custom spawn data
public class CardSpawnData extends SpawnData {

  private Suit suit;
  private Rank rank;

  public CardSpawnData(double x, double y, Suit suit, Rank rank) {
    super(x, y);
    this.suit = suit;
    this.rank = rank;
  }
  ...
}

If you have any other ideas on how to achieve this, please let me know
