Open new browserTab _system not working correctly

[engharb]

Hi,

I tried the following:

// in constructor : private browserTab: BrowserTab,
this.browserTab.isAvailable().then(
            isAvailable => {

                if (isAvailable) {
                    this.browserTab.openUrl(
                        "myTestUrl"
                    ).then(onfulfilled => {
                        alert("Succeeded");
                    }).catch(err => {
                        alert("errorrrrrr");
                    });
                }
            }
        ).catch( err => {
            alert(JSON.stringify(err));
        });
`
``
I want to keep an event listener to the opened tab in order to read i.e url or other features.

Unfortunately that is not possible. 

I'm using 
* Ionic-core:4
* angualr5
* typescript

Any suggestion?
