Working on a Veeam setup for our GCC High tenant. Trying to get email notifications setup. Found this information on pointing to GCC. Problem is I have no idea the format it's looking for in the value. I have tried a few different ways with no luck. Region is Virginia, but every way i have tried it says it doesn't like it.

OAuth 2.0 support for nonstandard Azure regions, including the U.S. Government, China, and Germany, is now available for email notifications. To enable this, create the following registry value on the Veeam Backup Server:

Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\
Value Name: EmailNotificationMicrosoftCloudInstance
Value Type: String Value (REG_SZ)
Value Data: <desired_region_name>
