I am trying to pass custom deeplink params from one application to another.

**Caller Application code**

```auto
// Launching app with parameters
var request = webOS.service.request('luna://com.webos.applicationManager', {
  method: 'launch',
  parameters: {
    id: 'com.yourdomain.callee',
    params: {
      customParam1: 'value1',
      customParam2: 'value2'
    },
  },
  onSuccess: function (inResponse) {
    console.log('The app is launched');
  },
  onFailure: function (inError) {
    console.log('Failed to launch the app');
    // To-Do something
    return;
  },
});

```

**Callee Application code:**

```auto
// webOSLaunch event
document.addEventListener('webOSLaunch', function(inData) {
    // Check the received parameters
    console.log(JSON.stringify(inData));
    // Do something in the foreground
    ...
}, true);

```

On webOSLaunch event we got “{‘isTrusted’:false}” instead of customParams we are sending from caller application.

Please guide as we need to receive customParams in callee application

Please refer to [webOSTV.JS Library](https://github.com/webOS-TV-app-samples/webOSTVJSLibrary) sample app. This app shows how to launch an app on the other app and works without issues. Thank you.
