Debug Output/Panic Output

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform will perform the following actions:

  # module.windowsappservice["xyz"].azurerm_windows_web_app.webapp will be updated in-place
  ~ resource "azurerm_windows_web_app" "webapp" {
        id                                             = "id"
        name                                           = "xyz"
        tags                                           = {}
        # (25 unchanged attributes hidden)

      + backup {
          + enabled             = true
          + name                = "xyz"
          + storage_account_url = (sensitive value)

          + schedule {
              + frequency_interval       = 1
              + frequency_unit           = "Day"
              + keep_at_least_one_backup = true
              + retention_period_days    = 60
              + start_time               = "time"
            }
        }

        # (4 unchanged blocks hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.

Expected Behaviour

Created Custom Backup should have "Backup/restore over virtual network Integration" Option Enbaled. "vnetBackupRestoreEnabled": true

Actual Behaviour

"vnetBackupRestoreEnabled": false

Since this option is not True/Checked, my backups are failing as the destination Storage account has firewall turned on and can be accessed only from the Vnet.

Steps to Reproduce

terraform apply

Also, I couldn't find any option in the backup block of azurerm_windows_web_app to set "Backup/restore over virtual network Integration" True or False.
