Is it possible to hide image URLs in AppSheet-generated PDFs?

[mars_yeh7334]

Hi everyone,

I’ve built an expense request form in AppSheet that generates a PDF after manager approval, including the manager’s signature image. However, I noticed that the image URL in the PDF is publicly accessible—anyone with the link can download the signature image.

Is there any way to hide or protect the image URL in the generated PDF to prevent unauthorized access?

Thanks in advance for your help!
