Mobile > From any mobile app, user should be able to send a file in Nuxeo app

For a mobile App, on a file, I click on the 'send to' icon and I see a list of applications where I can send the file to.
I click on Nuxeo.
I am redirected to the Nuxeo mobile app, on the nuxeo 'dropbox',where all the files are stored.
I go where I want in the repository (using the hierarchy), I click 'create' and I can upload a local file that has been exported to the 'dropbox'
