You can achieve that by installing the NPM package pdfkit, and write some backend code to build your document.
To install the package, on the left panel, click the plsu sign (+) next to “Backend”, and choose “install node package”. Then search for pdfkit, and install it.
Next, you can write in your backend code:
import pdfkit from "pdfkit"
and then follow the code instructions here: http://pdfkit.org/
Good luck
