Ionic 3 Download Plugin How to Hide Source URI

I am using Download plugin on ionic 3 to natively download pdf file from an external source. Here is the code I am using.

var request = {
      uri: item.url,
      title: item.resource_title,
      description: '',
      mimeType: '',
      visibleInDownloadsUi: false,
      notificationVisibility: 1,
      destinationInExternalFilesDir: {
          dirType: 'Downloads',
          subPath: 'MyFile.pdf'
      destinationUri: 'this.file.externalRootDirectory + ‘/Download/’',
          .then((location: string) => console.log('File downloaded at:'+location))
          .catch((error: any) => console.error(error));

In the above code “item.uri” is an external download link like

Now the problem is that whenever a user downloads this file, he can see the source url ( in the download manager.

I was thinking is there a way we can hide this source uri or show some dummy text in the download manager. I can see that other apps like google and skype do that.
