Unshare Files and Folders using script from Google Drive

Question

I was trying to unshare Files and Folders which are in the Google Drive using scripts mentioned in these links Google Drive Link Unshare https://github.com/HR/google-drive-unshare/blob/unshare-all/Code.gs

Execution Logs shows

11:16:53 AM Notice Execution started 11:16:53 AM Notice Execution completed

But still able to see the Folders and Files are still showing shared.

What exactly I am missing here?

Please help.
