 - it does unnecessary modifications on the documents, so you cannot simply do something like Get-Document | Update-Document
   - it adds props like attachments, timestamp, etc and those properties get written back to DB if you are not careful, bloating the doc with unwanted duplicate data
 
-So I ended up with this module that contains just data manipulation routines, is designed primarily for Core edition of PowerShell and uses OAuth authetication (no plans to add access key based auth)

 For Azure Managed identity, supported environments are Azure VM and Azure App Service / App Function / Azure Automation - all cases with System Managed Identity and User-assigned Managed Identity.

 Authentication allows separate credentials for every Cosmos DB account, so in single script / powershell session, you can connect to multiple Cosmos DB accounts and databases with different credentials at the same time - just store connection returned by `Connect-Cosmos` command in variable and use it as needed.
