how to make an onclick to another class in OneSignal

I want to make OneSignal open another activity in android studio. Follow the activity with the handler.

    OneSignal.startInit(this)
            .setNotificationReceivedHandler(new PlocarNotificationReceivedHandler())
            .setNotificationOpenedHandler(new PlocarNotificationOpenedHandler(PrincipalActivity.this))
            .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.None)
            .init();

public class PlocarNotificationReceivedHandler implements OneSignal.NotificationReceivedHandler {
    @Override
    public void notificationReceived(OSNotification notification) {
        JSONObject data = notification.payload.additionalData;
        String customKey;

        if (data != null) {
            customKey = data.optString(getResources().getString(R.string.action_display_campanha), null);
            if (customKey != null) {
                Intent broadcast = new Intent();
                broadcast.setAction(getResources().getString(R.string.action_display_campanha));
                broadcast.putExtra("id_campanha", customKey);
                sendBroadcast(broadcast);
            }
        }
    }
}

public class PlocarNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler {

    private Context context;

    public
    PlocarNotificationOpenedHandler(Context context) {
        this.context = context;
    }

    @Override
    public void notificationOpened(OSNotificationOpenResult result) {
        OSNotificationAction.ActionType actionType = result.action.type;
        JSONObject data = result.notification.payload.additionalData;
        String customKey;

        if (data != null) {
            customKey = data.optString(getResources().getString(R.string.action_display_campanha), null);
            if (customKey != null) {
                Intent myNewActivity = new Intent(context, LoginActivity.class);
                myNewActivity.putExtra("id_campanha", customKey);
                startActivity(myNewActivity);
            }
        }
        if (actionType == OSNotificationAction.ActionType.ActionTaken) {
            Log.i("OneSignalExample", "Button pressed with id: " + result.action.actionID);
        }
    }
}
