Company app lockdown - eviltoast

I work for a large multi national and they won’t let me download the remarkable app which is fairly obvious. But what is the best way to:

  1. Import PDFs to the remarkable without the desktop app? Generally these will be market research docs, articles, nothing sensitive
  2. Export notes or at least view notes on my laptop? Generally will be diagrams, general notes or annotated PDFs

My work have OneDrive but not sure if the integration by default would work.

What is the best way to make it as productive as possible? Also, anyone know a way of screenshots without the desktop App?
