PDF viewer control (experimental) in Power Apps
An experimental control that shows the content of a PDF file.
Description
Show text, graphics, and other content in a PDF file by adding this type of control and setting its Document property to the URL, enclosed in double quotation marks, of the file that you want to show.
Limitations
The PDF viewer control only supports PDF files that conform to the PDF32000 specification.
The security architecture of Power Apps requires the PDF Viewer to support only HTTPS links, not HTTP.
The Document property must link directly to the PDF file. Server redirects or HTML views of the document aren't supported.
The file must be accessible anonymously without any authentication.
You can't view a PDF document in your app if the document resides on a server that has restrictive cross-origin resource sharing (CORS) settings. To resolve this issue, the server that hosts PDF documents must permit cross-origin requests from powerapps.com.
Embedded objects like scripts and buttons don't run.
Printing the document isn't supported.
App users can work around these limitations by opening PDF documents in an external browser, as prompted if the control can't open a document. This option is also available in the control menu for all external documents.

Accessibility guidelines
Not all accessibility features of PDF documents are supported because the PDF viewer is still in the experimental stage. Therefore, ShowControls should be set to true to allow users to open the document in an external application.
Learn how to create accessible PDF documents with the Web Content Accessibility Guidelines (WCAG) 2.0 and PDF/UA standards.
Screen reader support
Consider adding a heading using a Label, if the PDF document doesn't have a title. The heading can be positioned immediately before the PDF viewer.
