Wopiframe hide links to sharepoint library

Hi 

I am using wopiframe as iframe on a webpage.

The doc loads properly but I cant find a way to hide the link to its original document library.

I am calling theis wopiframe from another web page not from the doc library.

When I try to access the elements using DOM, i get access denied error at iframe element.contents() of the wopiframe.

Any other choices?

Thanks
