[@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

まず、@nativescript/local-notifications 6.4.0、@nativescript/android 8.9.1、@nativescript/firebase-messaging 5.0.2 を使用して Android の動作を再現します。LocalNotifications.hasPermission()、requestPermissions()、firebase().messaging().requestPermission() を追跡します。付与された通知権限が認識され、LocalNotifications.schedule が Permission not granted で失敗しなくなれば完了です。
