PDF doc would not show up

Hello,

I am making a site that shows PDF and I am trying to use the PDF Viewer plugin. The site does not show the document.

Can someone please point me to what is going wrong?

My shortcode: [pdfviewer width=”600px” height=”849px” beta=”true”]https://wemakeapieceofcake.com/wp-content/uploads/2021/01/pdf1.pdf[/pdfviewer]

Thanks
