Follow this guide and just change image/* to application/pdf

Guide :point_down:

Use content:/ instead of file:///

i got that fixed from a post by @Taifun
i have one more problem i used Filetools extention by @vknow360 to convert uri to path
and i have put it on a label.

but it says operation Text cannot accept *[nothing]*
