React-native-onesignal: null is not an object evaluating 'RNOneSigna l.setAppId'

[astroana]

I have created an account at Onesignal website and got my App ID,
and installed react-native-onesignal version ^4.0.3.
React Native ver: 0.63.4

Copy pasted the config on the documentation

useEffect(() => {
/* O N E S I G N A L   S E T U P */
  OneSignal.setAppId("MY_APP_ID");
  OneSignal.setLogLevel(6, 0);
  OneSignal.setRequiresUserPrivacyConsent(false);
  OneSignal.promptForPushNotificationsWithUserResponse(response => {
    OSLog("Prompt response:", response);
  });
}, [])

But im getting error:
null is not an object evaluating 'RNOneSigna l.setAppId',

The same here, the documentation is incomplete and only available in class components, 2021 using clases, yep: Onesignal.
The second if you browse into the /examples you will only find in TS.

Use this repo, it's better than Onesignal:

Thanks for the example it was helpfull, I also got it working now I just redo the installation and the linking,
this might also help for android:

build.gradle
------------------------------------------------

buildscript {
    repositories {
        maven { url 'https://plugins.gradle.org/m2/' }
    }
    dependencies {
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.12.9, 0.99.99]'
    }
}

app/build.gradle
-------------------------------------------------

apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

dependencies {
 ......
implementation 'com.google.android.gms:play-services-location:+'
 ......

-------------------------------------------------------------------
androidmanifest.xml add android:launchMode="singleTask"
-------------------------------------------------------------------

 <activity
    android:name=".MainActivity"
    android:label="xxxxxxxxxxxxxxxxxx"
    android:launchMode="singleTask"> <!-- Add this attribute to your main activity -->
  </activity>

Then I initialized using the sample from @TrejoCode
