Question

I am using Jovo framework to develop Google-assistant actions

Here is the scenario I need,

1. Talk to My Notes. Add "Hello world"

2. Using Jovo framework and dialogFlow fullfillment, I captured ADD intent

    app.setHandler({

  ADD() {
    if (!this.getAccessToken()) {
            this.googleAction().showAccountLinkingCard();
        } else {
     this.toIntent('WelcomeIntent');
  }
});

module.exports = { app };

Now I want open my app with "Hello world" as parameter using deeplink

Could someone help me how can I open app/url from jovo framework
