Page Viewer Web Part File Link Format
Struggling to insert the value acceptable to the Page Viewer web part Link property. It's a PDF in Site Assets doc lib, and that PDF may be switched in and out or otherwise updated and overwritten by drags and drops and other things. The https://support.microsoft.com/en-us/office/display-a-web-page-folder-or-file-on-a-classic-sharepoint-page-7f61feec-9b3d-4805-a960-07636ba59527 say there is a Browse function that can be "select"ed, but I don't see it in the Page Viewer property panel where Link is. I prefer to use this rather than a Script Editor web part, because users not advanced who may maintain it and change documents don't want to struggle inserting iframe elements and understanding what UniqueId attributes are and how to get them and maintain them. I am creating an app for "updating" these snippets, but this app may break, and they are not advanced users. I want them to manipulate the web part with minimal understanding and effort
