Zoho Embedded App JS SDK - use ZOHO.CRM.CONNECTION.invoke() to upload file to WorkDrive

I have been attempting to use the Zoho Embedded App JS SDK to create a widget, and using a CRM connection (ZOHO.CRM.CONNECTION) to communicate with WorkDrive. The client that the application is being developed for requires the widget to be able to upload files - I have been trying to use ZOHO.CRM.CONNECTION.invoke() to pass file data to WorkDrive with no success. I am attempting to use the workdrive API detailed here. Is there a method to POST file data to WorkDrive using ZOHO.CRM.CONNECTION.invoke()? (note that I am referring to CONNECTION, not CONNECTOR.)
