I want to use 'pdftools' package in shinyapps.io

If I use 'pdftools' package in RStudio, it is fine. But if I use 'pdftools' package in shinyapps, it is troubling with stopped page. I found that trouble is from version of 'poppler' which required from 'pdftools'. shinyapps is installed version 0.41 in default system packages, but 'pdftoos' need upper than 0.73. What should I do? Can I change this version for my app??
