I'm trying to save the form data with a pdf that's being display with react-pdf. My current setup is calling the pdf bytes as a base64 string from a database entry, and loading the pdf through canvas. I've got all the necessary functions to save the actual data as strings, but I don't know how to "save" the pdf with the form fields saved with the pdf. Does someone know this last step?

<div>
<Document
  file={{
    data: fileBytes,
  }}
  onLoadSuccess={onDocumentLoadSuccess}
  options={options}
>
  <Page
    renderForms={true}
    pageNumber={pageNumber}
    onClick={setVariable}
    onInput={setVariable}
    canvasRef={canvasRef}
  />
</Document>
<p>
  Page {pageNumber} of {totalPages}
</p>
</div>
