How to check if the user successfully save an image using media.save()?

After checking the documentation( it seems like media.save() doesn’t have a callback return value. How can i check if the user successfully saved the image? My concern is that if the user rejects the photo permission the first time he wont be able to save an image unless he/she changes the permission manually in the settings. I want to be able to tell the user that it needs to change its settings if the image fails to save.
