    if (Capacitor.isNativePlatform()) {
      this.debug('native');
      // if it is native
      await this.registerNotifications();
    } else {
      Notification.requestPermission().then((permission) => {
        this.debug('Notification permission granted.', permission);
        if (permission === 'granted') {
          this.debug('Notification permission granted.');
          this.getToken();
        }
      });
    }
  }

  async registerNotifications() {
    let permStatus = await PushNotifications.checkPermissions();

    if (permStatus.receive === 'prompt') {
      permStatus = await PushNotifications.requestPermissions();
    }

    if (permStatus.receive !== 'granted') {
      throw new Error('User denied permissions!');
    }

  };

undefined is what the register method returns, that's not a bug

if you are not receiving the push notification token it's probably some misconfiguration in your app

Make sure you added push capabilities and this two methods in your AppDelegate.swift as explained in the docs

Also add the registrationError event listener as if it's failing to register, it will provide more information about what the problem is.
