I can't get Cryptomator to work with either of my cloud providers - can someone take a look at my setup and give me some advice?

Hi there. Maybe I should try and explain the situation using a different approach. I save all of my new documents to the local “My documents” folder (I’m running Windows 10). I never save files directly to the cloud folder, be it my OneDrive folder or Dropbox folder. How do I take these local files, stored in the “My documents” folder, and make it so that those files are backed up and synced to Dropbox/OneDrive/Sync/whatever cloud provider I choose and encrypted with Cryptomator. I would like to be able to work on the documents that are locally stored in the My documents folder and have any changes made to those documents mirrored in the copies saved to my Cryptomator vault.
