Ionic Native Media plugin file status

Ionic Native Media plugin documentation here says it has some static members and instance member like status.

But , how to use them ? There should have been at least one example.

I tried this ,

console.log(this.file.status);

returns {"_isScalar":false}

this.file.status.then((status)=>{
          console.log('status 2 :' + status)
        });

returns this.file.status.then is not a function

this.file.status.subscribe((status)=>{
          console.log('status 3 :' + status)
        });

subscribe doesn’t log anything

How do i get the file status ? and also how can static members be used to get file status ?

@brandyshea @mhartington anything on this ? I didn’t want to tag but , but its been 2 days and still stuck on this.
