How can I submit a PDF assignment that I exported to my Canvas file folder?

I scanned an assignment as a PDF and exported it into Canvas "My Files." When I click on "Submit assignment" on the course assignment submission page from my Android phone, the little panda bear page tells me to "select a file from the options below," but none of the options below gets me into My Files. The "options below" are the Canvas Dashboard, Calendar, To-Do list, Notifications, and Inbox. How do I get to "My Files" from a mobile device? (I can do it from my laptop, but we are being asked to submit quizzes without touching our laptops...)
