Create apps script that lists all documents (files) that are shared outside of organization?

[bogart]

Hey,

Trying to create  a very simple Apps Script that should list all documents (files) that are shared outside of our organization. Would love to have them all listed by; document id document name, shared folder name and if it's shared using link and / or mail. 

Any simple way of doing this? Seems relatively easy to do for my own docs but not sure about domain-wide. 

Thanks
