I can't get a FCM click action to work on IOS PWA

Question

The notifications clicked work fine on both android (installed PWA) and chrome but in ios, I haven't had success, At the moment we set the "category" parameter in the payload and the additional actions on the notifications but I have not been able to perform a clicked when the notification is clicked. Is there a way to send actionable notifications to iOS devices?

Sample JSON of message payload:

{
    "to": "cadyI6R8vE27vTOfjE157N:APA91bFIEkJqcHzHex9qOOB3eDGWnKg8Fv74iTgDcJDsUVha81hdtphy1fnPDa7rFlRcK48L8vJkthzOp3NyEd_cvSbOcJ4eI335K2N9I-E8ZfA85_2_OnP02OO8vfGv0Gxzz2ACtfSF",
    "collapse_key":"type_a",
    "notification":{
        "title":"Le Soir d\u2019Alg\u00e9rie",
        "body":"Justice : Le proc\u00e8s de Chakib Khelil pr\u00e9vu aujourd\u2019hui",
        "icon":"/images/favicon.png",
        "click_action":"https://www.lesoirdalgerie.com/actualites/les-graves-accusations-de-benbahmed-80545",
        "sound": "default"
    },
    "apns":{
        "payload":{
            "aps":{

                "category":"GENERAL"
            }
        }
    }
}

Here is my AppDelegatecode :

        FirebaseApp.configure()

        // [START set_messaging_delegate]
        Messaging.messaging().delegate = self
        // [END set_messaging_delegate]
        // Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        // [START register_for_notifications]
   
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })


        application.registerForRemoteNotifications()

Any help would be greatly appreciated since I have not found a single thing that would help me understand this.
