Realtime for specific collection

void _subscribeToSubmittedMediaAppend() {
    final realtime = Realtime(client);
    realtimeMediaValidationSubscription = realtime.subscribe(
        ['databases.$appDatabase.collections.$roomMediaCollection.documents']);
    // Listen to changes
    realtimeMediaValidationSubscription?.stream.listen((event) {

Developers are trying to implement realtime updates for a specific collection in their Dart code, but the function is not being called. The issue might be related to how the `subscribe` method is being used. To fix this, developers should ensure that the subscription path is correct by verifying the database, collection, and document names. Additionally, they should double-check that the Realtime client is properly initialized and connected.
