How to install external library in frappe

i am trying to install external library

pdfplumber==0.10.3
PyPDF2==3.0.1
its working in my local system

but when i deployed in frappe cloud then its not working

@Pkolhetkar
Try this Invalid pyproject.toml file
Also am not sure but I assume that you can only install external dependencies if you are on a private bench

Thank you so much sir
