Cannot delete selected folders from a Windows 11 client via SMB

Discussion is here;

How do I DELETE a directory wheb I do not have that particular user anymore?

I successfully migrated my established POOL from an old (failing) home-brew platform to a new TrueNAS CORE Mini. There are 2 sub directories created by Microsoft Backup application- and I would like to DELETE them both. Since they were created on my old Truenas platform, and by a user ID other than me- they refuse to allow me to delete them. I operate my NAS here in my own home on my own LAN, and I would like to be able to use SUDO commands to delete these large sub directories.
