How to take secure, on-demand backups on SQL Managed Instance

Hi,

This document https://learn.microsoft.com/en-us/sql/relational-databases/backup-restore/sql-server-backup-to-url?view=sql-server-ver16#limitations-of-backuprestore-to-azure-blob-storage seems to say pretty explicitly that using managed identities for backup/restore to storage accounts is not supported:

"Backup to Azure Storage account only supports authentication with Shared Access Signature (SAS) tokens or storage account keys. All other authentication methods, including authentication with Microsoft Entra ID (...), aren't supported."

Do you think that document is outdated/incorrect, or was the solution described in this blog entry supported for a while but is not any longer, or am I somehow misreading it?

thanks!

Martin
