title: Ionic 5 + Capacitor with Huawei HMS
body: <p>I've build an app using Ionic 5 (Angular) and Capacitor. I'm using the Capacitor plugin for Push Notifications. All is working fine on both iOS and Android. However on Huawai phones (P30 and later) things don't work properly.</p>
  <p>No device id is obtained and Push Notifications don't work, even the PushNotifications.addListener('registration', async (token: PushNotificationToken) =&gt; {}) is not triggered.</p>
  <p>Any ideas on what I need to do so that I can maintain one codebase and make it work on both Android &quot;worlds&quot; (Google &amp; Huawei) ?</p>
  <p>Thanks in advance,
  Chris</p>
