Post to Adobe Aero from Google Drive

Hi, 

I haven't user Aero in about a year. I am using it in an academic setting. When I last taught Aero, students could import assets from Google Drive. This page says it's possible. But I don't see an option in the iPhone Aero app. 

Do I need to save the asset in the Google Drive app to files, and then import it from there? Or is there another workflow? 

Thanks
