How to upload document from checkout page to one drive in magento2

I am adding a new input field(file uploader) to one step checkout page. This file will be stored in one drive. I want users from my website to be able to upload a file to a specific one drive folder on my one drive account, So my one drive account will work as a storage drive. They can upload files during checkout. I have also registered an app on the Microsoft azure directory and gave the necessary permissions. Can anyone guide me on how to proceed with this functionality? Thank you in advance.
