I've read that it's possible for a student to turn in a google document as an assignment submission, but I don't know how to make that work. Please refer to what I pasted below. Any suggestions?
File Uploads : Students can upload a file to fulfill the assignment. Note that if your institution has enabled Google Docs as a submission type, students canconnect to Google Docs as a web service to submit an assignment as a Google Doc, Google Sheet, or Google Slide. However, these files will convert to their Microsoft counterpart file type—Word, Excel, and PowerPoint, respectively.
