Code Push functionality not working for react native app

I am new to code push and react native, I followed the steps given in the official docs- https://learn.microsoft.com/en-us/appcenter/distribution/codepush/react-native#getting-started, but even after pushing code to appcenter, it is not updating the app. Please find below the necessary code.

Index.js

import 'react-native-gesture-handler';
import {AppRegistry} from 'react-native';
import App from './App';
import {name as appName} from './app.json';
import codePush from 'react-native-code-push';
let codePushOptions = {checkFrequency: codePush.CheckFrequency.ON_APP_START};
AppRegistry.registerComponent(appName, () => codePush(codePushOptions)(App));

MainApplication.java

package com.awesomeproject;

import android.content.Context;

import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.soloader.SoLoader;
import java.lang.reflect.InvocationTargetException;
import java.util.List;

public class MainApplication extends Application implements ReactApplication {

  private final ReactNativeHost mReactNativeHost =
      new ReactNativeHost(this) {
        @Override
        public boolean getUseDeveloperSupport() {
          return BuildConfig.DEBUG;
        }

        @Override
        protected String getJSBundleFile() {
          return CodePush.getJSBundleFile();
        }

        @Override
        protected List<ReactPackage> getPackages() {
          @SuppressWarnings("UnnecessaryLocalVariable")
          List<ReactPackage> packages = new PackageList(this).getPackages();
          // // Packages that cannot be autolinked yet can be added manually here, for example:
          // packages.add(new MyReactNativePackage());
          return packages;
        }

        @Override
        protected String getJSMainModuleName() {
          return "index";
        }
      };

  @Override
  public ReactNativeHost getReactNativeHost() {
    return mReactNativeHost;
  }

  @Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
    initializeFlipper(this, getReactNativeHost().getReactInstanceManager());
  }

  /**
   * Loads Flipper in React Native templates. Call this in the onCreate method with something like
   * initializeFlipper(this, getReactNativeHost().getReactInstanceManager());

   */
  private static void initializeFlipper(
      Context context, ReactInstanceManager reactInstanceManager) {
    if (BuildConfig.DEBUG) {
      try {
        /*
         We use reflection here to pick up the class that initializes Flipper,
        since Flipper library is not available in release mode
        */
        Class<?> aClass = Class.forName("com.awesomeproject.ReactNativeFlipper");
        aClass
            .getMethod("initializeFlipper", Context.class, ReactInstanceManager.class)
            .invoke(null, context, reactInstanceManager);
      } catch (ClassNotFoundException e) {
        e.printStackTrace();
      } catch (NoSuchMethodException e) {

Please let me know, if there's anything else need.

I got the solution, I had React native version 0.62 and code Push only supported react native version 0.61 and below at the time I made this post. So I just downgraded the version to 0.61 and now codePush is working fine.
