Preview of Embedded Objects Is Not Coming in Microsoft PowerPoint

Hello Team,

Our business need is to enable user to select Prism and Excel objects via a web application and create an MS Powerpoint using the application with the selected objects embedded in it and have a preview of the object content in the PPT.

Currently we are able to achieve the embedding of the objects (Excel & Prism) in the PPT, using Aspose Cloud API, but the preview part is not working as expected. Attaching is the sample PPT generated.
Sample PPT.zip (5.5 MB)

Could you please provide assistance in the preview part of the objects? This is the only pending piece of achieving our business case.

Thanks for support. This is critical for go live next week.
