Add PDF as document type to the new Document webpart on Modern Pages
Only Word, Excel, PowerPoint and Visio are supported document types for viewing in the new Document webpart on Modern Pages.
PDF is a widely used way to share documents that are closed for editing and it would be great to show these as well.
The lack of viewing PDF Files in modern pages is a real showstopper.
Please add PDF Filetype to the modern File Viewer. This is actually a NO GO! It is implemented in SharePoint Online, but not on premise. This must be a tactical decision. Shame on MSFT.
