send pdf to another browser tab

I'm working on a shiny app where the user enters data across multiple tabPanels (using next and back buttons) and on the final tabPanel it presents a summary of their selections. I've placed a button on the last tabPanel that utilizes capture_pdf. It works great except that if I browse back to the app after the pdf has loaded, the app reloads and all the user input is lost. I'm wondering if there's a way to send the pdf to another browser tab so that the user can revisit the app w/o losing the previous entries.

Appreciate any help you can offer!
