Missing description field for Azure Firewall Policy Rule Collection Group rules

In the reference documentation for creating rules in rule collection groups in Azure Firewall Policy the `description` field is listed as valid for individual rules: https://learn.microsoft.com/en-us/azure/templates/microsoft.network/firewallpolicies/rulecollectiongroups?pivots=deployment-language-bicep#firewallpolicyrulecollection-objects

However, the `description` property is not visible in the portal, or when querying rules with PowerShell, even when the rules are deployed with this property set.

Is this an error in the API definition/resource schema?

Would be very useful if this property is

1) Actually represented in the resource properties in Azure

2) Visible in the portal (via Firewall Manager)
