How to disable copy paste on pdf.js when it is embedded on Thinkific

[tonystanislas]

I hope you are well,

Does someone know how to disable the copy paste feature on the pdf.js pdf viewer when it is embedded on the Thinkific https://thinkific.com/ platform ?

I disabled the copy and paste option on a pdf thanks to Adobe Acrobat Pro's protection feature
I uploaded it on the Thinkific platform using their embedded pdf viewer pdf.js
While the protection works when I open the pdf with Adobe Acrobat Pro (I am not able to copy paste anymore), the protection does not work on the Thinkific embededded pdf viewer pdf.js (I am still able to copy paste content from the pdf).

How can I sort this out ?

Thank you
