The upload method in flowjs is not defined

I am a novice when it comes to flow.js and am currently using the ng-flow implementation. I have a specific task in mind, but I'm unsure if it's feasible or not, and if it is possible, how to achieve it. I've created a factory that captures all events, and I require it to automatically upload a file when it detects the FilesSubmitted event. Despite referencing the flowJs documentation here, I have been unable to locate the upload() method when logging the 'file' element in the console. It seems as though the method does not exist. I had assumed that perhaps the resume() function was calling the method internally, but that didn't work either.

In accordance with the official guidelines:

<div flow-init="{target: '/upload'}" flow-files-submitted="$flow.upload()"></div>

When 

flow-files-submitted="$flow.upload()"
is configured alongside flow-init, the file will automatically start uploading once it is chosen from the selection menu. If you decide to remove this setting, a separate button (similar to Pause/Resume/Cancel) must be created and linked to upload() for manual initiation of the upload process.

An example would be:

<button ng-click="$flow.upload()">Upload</button>
<button ng-click="$flow.pause()">Pause</button>
<button ng-click="$flow.resume()">Resume</button>
<button ng-click="$flow.cancel()">Cancel</button>
