When app is in foreground, the same push notification is sent twice to the AppDelegate

[yousrasd]

I have an app where I'm using this library to handle incoming push notifications.

When the app is in the foreground on iOS devices, my AppDelegate's willPresentNotification method is called twice. The first time, it is called with the complete data in UNNotification (I send custom data through Firebase Messaging). However, the second time it is called, it only contains the notification subject and body, without the custom data I sent.

I'm unsure why my AppDelegate's willPresentNotification method is being called twice. Also, when it is called the second time, the following method is called

ios/ios/RCTConvert+Notification.m

Line 111 in 4979f60

+ (UNNotificationRequest *)UNNotificationRequest:(id)json

Who is calling this [RCTConvert UNNotificationRequest]? I dont seem to find it in this lib.

here is my AppDelegate:

#import "AppDelegate.h"
#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <React/RCTAppSetupUtils.h>

  bridge.surfacePresenter = _bridgeAdapter.surfacePresenter;
#endif

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  [RNSplashScreen show];
  // Define UNUserNotificationCenter
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  center.delegate = self;
  
  return YES;
}

{
  // allow showing foreground notifications
  completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge);
}

Any help would be appreciated. Im trying to understand why Im getting this behavior. Normally, my AppDelegate method should only be called once, and right after the push notification should appear. But this is not what's happening.

try to touch/tap the localNotification notification, you will get the listener triggered
