Opening Facebook app from ionic using username not ID

Question

I'm trying to open the facebook app using my username on my ionic project but it doesn't work. I'm using InAppBrowser and AppAvailability on my project.

Here is my current implementation:

openFacebook(name, url) {
  let app;
  if (this.platform.is('ios')) {
    app = 'fb://';
  } else if (this.platform.is('android')) {
    app = 'com.facebook.katana';
  } else {
    this.openInApp('https://www.facebook.com/' + name);
   return;
  }
  this.appAvailability.check(app)
    .then(res => {
      const fbUrl = 'fb://facewebmodal/f?href=' + url;
      this.openInApp(fbUrl);
    }
    ).catch(() => {
      this.openInApp('https://www.facebook.com/' + name);
    });                                                                                        
}  
                                                           
private openInApp(url) {
  this.inAppBrowser.create(url, INAPP_TARGET.system);                                           
}

This implementation redirects to the Facebook app but not on my profile it just shows the News Feed (Just like when you open the facebook app manually). Please note that I am trying to open any profile with the Facebook app using a username.
