Photo Library path in ios

I’m currently developing an application on ionic 3 for ios that saves an a photo captured from from the camera to the photo library, then changes it’s name.
I currently managed to do all the app, using the cordova camera and the photolibrary plugins.
But to change the file name, i assume I’ll need the cordova file plugin, exactly the method file.moveFile, but the issue is I don’t know the photolibrary path. Does anyone know what’s the file:///… path to the photo library on ios ?
