Question

I am trying to pull Site/List/Library/Item/subsite level permissions/unique permission on our SharePoint online site using the script below from reference :

However, I am getting site/subsites level permission only in PNP Powershell using above code. I tried to work on scripts in PNP to get list and library permission/unique permission but unable to find an idea. If anyone could help me to extend same code, it would be greatly appreciated.
Thanks in Advance!!
Please check below code:
