Updated: Sep 27, 2020
This script is capable of pulling the permission report for a specific site and can be used to audit the permissions on SharePoint online.
It queries all list and libraries to fetch the permissions details and gives a detailed report in the form of excel sheet.
The PNP PowerShell script is as below for reference and kindly modify the highlighted part in script before running it:
#Function to Get Permissions Applied on a particular Object, such as: Web, List, Folder or List Item

{
$ObjectType = "Folder"
#Get the URL of the Folder

$ObjectURL = $("{0}{1}" -f $Web.Url.Replace($Web.ServerRelativeUrl,''),$Object.Folder.ServerRelativeUrl)
}
