Advanced Document Viewer Tile is not showing videos embedded within the previewed document. You want to know how you can display a video on the home page to a subset of users only, and not all users.
Advance Document Viewer Tile does not support Video Preview.
If you wish to preview documents with videos in a tile, please use the 'document viewer tile' instead.
Note: The Document Viewer Tile does not have Visibility Rules. If you would like to customize the audience of a tile, you would need to engage professional services, which may incur an additional cost. If you would like to do this, please contact your Account Management Team through firstname.lastname@example.org.
