Help notification banner PWA on Android device

[kae90]

Hi, from the ESP8266 I send the FCM notification to my PWA, but I can't make the notification appear as a "banner"; I only see it in the top bar.
Is there an option to enable notifications on PWAs?
Here's what I currently use to increase the priority.

SERVICE WORKER :
----------------------------------------
// Initialize Firebase
initializeApp(firebaseConfig);

self.addEventListener('install', (event) => self.skipWaiting());
self.addEventListener('activate', (event) => self.clients.claim());

// 🔹 Push event (ricezione notifiche background)
self.addEventListener('push', (event) => {
  const payload = event.data?.json() || {};
  if (!payload.notification) return;

  const { title, body, icon } = payload.notification;

  event.waitUntil(
    self.registration.showNotification(title, {
      body,
      icon: icon || '/app/Immagini/icon-192.png',

      // 🔥 AGGIUNTI (per aumentare probabilità banner)
      requireInteraction: true,
      silent: false,

      vibrate: [200, 100, 200],
      tag: 'alert-pwa',
      renotify: true,
      data: payload.data || {}
    })
  );
});



ESP8266 :
----------------------------------------
Messages::Message msg;
msg.topic(USER_UID);

{
Messages::Notification notification;
notification.title(DEVICE_NAME);
notification.body(message);
msg.notification(notification);
}
// --- FORCE BANNER ON ANDROID (PWA) ---
{
Messages::AndroidConfig androidConfig;
androidConfig.priority(Messages::AndroidMessagePriority::_HIGH);

Messages::AndroidNotification androidNotification;
androidNotification.notification_priority(Messages::NotificationPriority::PRIORITY_HIGH); 
// IMPORTANT: This ID must be unique or correspond to an "Urgent" channel 
androidNotification.channel_id(F("high_priority_channel")); 
androidNotification.default_sound(true); 
androidNotification.default_vibrate_timings(true); 

androidConfig.notification(androidNotification); 
msg.android(androidConfig); 
} 
Messages::Parent parent(FIREBASE_PROJECT_ID);
{ 
String payload = messaging.send(aClient, parent, msg); 
if (aClient.lastError().code() == 0) { 
Serial.println(F("✅ Notification sent successfully!")); 
saveFirebaseNotification(DEVICE_NAME, message);
} ```
