Copy items from Calendar list in each subsite to Calendar list in root site in SharePoint Online using CSOM PowerShell

I am trying to copy all items from Calendar list in each sub-site to the Calendar list in root site.

Here are my thoughts. Is it possible to make a CSOM PowerShell script for this?
