When embedding a PDF file using the format below a blank block appears without PDF viewer and the file can not be openend:
When opening Obsidian as admin the viewer is loaded correctly.
The console shows the below error when embedding the PDF:
Refused to display 'app://local/' in a frame because it set 'X-Frame-Options' to 'deny'.
This is on a work PC, so probably some settings are the reason for this behaviour. However this does really make much sense as this does not seem to be something that’s needs to be forbidden.
Maybe there is some workaround or even a way to not embed the PDF but instead open an external viewer when clicked?
