Comment faire pour que mon application WebView ouvre les notifications push d'UR

Bonjour
j ai instaler le plugins Onesignal sur mon site web wordpress et j ai configurer mon projet android studio avec onesignal et firebase, tous va bien . mais lorsque j'envoie une notification push avec mon site wordpress à ouvrir dans l'application webview, elle s'ouvre à la place dans le navigateur.

Est-il possible d'ouvrir les notifications push d'URL dans l'application et non dans le navigateur?

voila mon code MainActivity.java

public class MainActivity extends AppCompatActivity {
    WebView webView;
    ProgressBar progressBar;

    RelativeLayout relativeLayout;
    Button btnNoInternetConnection;

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_main);


        // OneSignal Initialization
        OneSignal.startInit(this)
                .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
                .unsubscribeWhenNotificationsAreDisabled(true)
                .init();


        webView = (WebView) findViewById(R.id.webView);
        progressBar = (ProgressBar) findViewById(R.id.progressBar );
        // loadUrl

        webView.setWebChromeClient( new MyChrome() );

        progressBar.setVisibility(View.VISIBLE);

         //apel telephone hort app
        webView.setWebViewClient(new WebViewClient() {
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                if (url.startsWith("tel:")) {
                    Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
                    startActivity(intent);
                    return true;
                }
                return false;
            }


            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                progressBar.setVisibility(View.GONE);
            }
        });


        //no connexion

        btnNoInternetConnection = (Button) findViewById(R.id.btnNoConnection);
        relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout);

        checkConnection();

//  websettings
        WebSettings webSettings = webView.getSettings();

        webSettings.setJavaScriptEnabled(true);
        //
        webSettings.setDomStorageEnabled(true);
        //
        webSettings.setUseWideViewPort(true);

        webSettings.setAllowContentAccess(true);
        webSettings.setAllowFileAccess(true);
        webSettings.setAppCacheEnabled(true);


// pivote ecran phone et video
        if (savedInstanceState!=null){
