Manifest merger failed in push notification

Question

I use native push notification in react and getting this error:

Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.

Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081

D:\F Drive\Sayalani React\React Native\basicgui\android\app\src\main\AndroidManifest.xml

Error: android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

The error message is pretty clear:

android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined

In your manifest file, there are several receivers that do not have the exported property:

<receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationActions" />
        <receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationPublisher" />
        <receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationBootEventReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.QUICKBOOT_POWERON" />
                <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
            </intent-filter>
        </receiver>
