3D FlipBook - Hide PDF file / no download

Hello,

I am using your great plugin as a pro version for years.

My special usecase is, that I give my customers a preview of my books in my onlineshop. Therefore I would like to show them the Flipbook - but make it not downloadable for them. At the moment they can fetch the URL from the file stream.

Do you have an idea how I could solve this?

thanks
