PowerPoint iFrame - Anyone with link

[BarryAnderson]

We have a PowerPoint file stored in OneDrive and sharing is set to "anyone with link".  However when this is embedded into a webpage there is a request to "Sign In" and signing in will allow the iFrame to display correctly.

1. We would like the PowerPoint to display to all users without a sign in.
2. The iFrame is hosted on a separate domain.

Can anyone provide guidance on what is causing this issue and possible solutions?  Is this related to CORS?

Thanks.
