Ionic View App – open local file in Powerpoint

Hey Guys,

in my test project in the Ionic View App i need to open a local file in the Powerpoint for iOS App (only for testing). I am trying it with this custom URL scheme:

javascript: document.location = 'ms-powerpoint://office/test.ppt'

It opens up Powerpoint as expected, but the file is not found. Is there an absolute path that i could use (iOS only)?
