Backup databases in SQL Server on Azure VM

I am using Azure Backup to backup a SQL Server on VM using the azurerm_backup_protected_vm resource. However, the backup management type inside Azure Recovery Services Vault after I deploy this resource is Azure Virtual Machine where I was expecting SQL in Azure VM. I do see that azurerm_mssql_virtual_machine resource has an auto_backup block but I am thinking that’s not necessary when Azure Backup is used instead. How do I backup the sql databases running on an Azure VM?
