Embedding PDF preview in Adobe Indesign panel

Hi there,

I'm trying to create an Indesign extension to display PDF content directly in it. I've tested the code to work fine in Chrome, but in Indesign it doesn't work. Instead alert says ```The application domain (file://) is not supported to use the provided PDF EmbedAPI Client ID```.

I've tried to get API key, but it sems it not allowed neither for localhost nor file.

Any help would be appreciated.
