Unable to change the Android push notification icon to the original one

Android with reference to Local Notifications Capacitor Plugin API | Ionic Documentation
I am trying to change the push notification icon in the status bar of the emulator to the original icon, but I cannot change it from the default icon.

{
  "@capacitor-community/fcm": "6.0.0",
  "@capacitor/android": "^6.0.0",
  "@capacitor/app": "^6.0.0",
  "@capacitor/browser": "^6.0.0",
  "@capacitor/camera": "^6.0.0",
  "@capacitor/core": "^6.0.0",
  "@capacitor/filesystem": "^6.0.0",
  "@capacitor/haptics": "^6.0.0",
  "@capacitor/ios": "^6.0.0",
  "@capacitor/keyboard": "^6.0.0",
  "@capacitor/local-notifications": "^6.0.0",
  "@capacitor/push-notifications": "^6.0.1",
  "@capacitor/status-bar": "^6.0.0",
  "@ionic/cli": "^7.2.0",
  "@ionic/core": "8.2.5",
  "@ionic/vue": "8.2.5",
  "vue": "3.4.31",
},

The following steps were attempted to set up the original icon.

  • Install @capacitor/local-notifications.
  • Store ic_launcher_round.png in android/app/src/main/res/drawable folder
  • Add the following to AndroidManifest.xml
<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
          <meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@drawable/ic_launcher_round" />
</application>
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
  • Add the following to capacitor.config.ts
{
  plugins: {
    PushNotifications: {
      presentationOptions: ["badge", "sound", "alert"]
    },

    LocalNotifications: { //add
      smallIcon: "ic_launcher_round",
      iconColor: "#fff",
    },
  }
}

When I send a notification, the document default icon is displayed as shown in the attached image.

Changing the meta-data tag in AndroidManifest.xml from drawable to mipm. ap did not change this.

<meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@mipmap/ic_launcher_round" />

One thing I am wondering is that only ic_launcher_round.png is shown in red in Android Studio.
Is this related to something else?

Please do let me know.
