### Feedback

Hi

This information is incorrect:
https://learn.microsoft.com/en-us/powershell/module/az.communication/new-azcommunicationservicekey?view=azps-14.1.0#-keytype

-KeyType
The keyType to regenerate. Must be either 'primary' or 'secondary'(case-insensitive).

should be:

-KeyType
The keyType to regenerate. Must be either 'Primary' or 'Secondary'(case-sensitive).

When primary or secondary is used with KeyType parameter it will fail with error "HTTP request payload failed validation against API specification with one or more errors. Please see details for more information."

But correct information is in example ... https://learn.microsoft.com/en-us/powershell/module/az.communication/new-azcommunicationservicekey?view=azps-14.1.0#example-1-regenerates-the-secondary-key-using-a-keytype

Also older version supported -parameter parameter this was removed without any information, release noted or warning.
