Hello there, I am using version 7.2.1

I am using `instance.downloadPdf();` to download pdf file. when I download a pdf file with this specified code the file is named as **document.pdf**. But I want to override the file name. How can I achieve that?

Hi there!

As per the [documentation](https://pdfjs.express/api/WebViewerInstance.html#downloadPdf__anchor), you can pass a `filename` option like so:

```javascript
instance.downloadPdf({
   filename: 'myfilename.pdf'
})

```

Thanks!  
Logan
