[@nativescript/localNotifications] - Android LocalNotifications.hasPermission() returns false after accepting notifications with firebase messaging

Info

"@nativescript/local-notifications": "^6.4.0",
"@nativescript/android": "8.9.1",
"@nativescript/firebase-messaging": "5.0.2",

Problem

Both LocalNotifications.hasPermission() and LocalNotifications.requestPermissions() return false in a application with already given permissions for push notifications. This does not allow for usage of the LocalNotifications.schedule with error
This piece of code
const authStatus = await firebase() .messaging() .requestPermission(<any>{});
console.log('Android - checking notification permissions ...', authStatus);
const aceptedLocalNotifications = await LocalNotifications.hasPermission();
console.log('Android - LocalNotifications.requestPermission', aceptedLocalNotifications);

returns
Android - checking notification permissions ... 0
Android - LocalNotifications.requestPermission false

Error

Error in LocalNotifications.requestPermission: Error: Permission not granted

首先使用 @nativescript/local-notifications 6.4.0、@nativescript/android 8.9.1 和 @nativescript/firebase-messaging 5.0.2 重現 Android 行為。追蹤 LocalNotifications.hasPermission()、requestPermissions() 和 firebase().messaging().requestPermission()；當已授予的通知權限能夠被辨識，且 LocalNotifications.schedule 不再因 Permission not granted 失敗時，即表示完成。
