Request approval for pending Network Security Perimeter preview feature registrations

We are trying to create an inbound access rule (Source type: Service tags) on a Network Security Perimeter (NSP) profile, and receive the following error in the Azure Portal:

Failed to create rule 'hdi' in profile 'defaultprofile'. This feature is not yet available for given subscription.

We identified that this requires two Microsoft.Network preview feature flags to be approved on our subscription. We have already submitted az feature register for both, but their registration state has remained Pending (not auto-approved) since

Subscription ID: 3a8f468f-5a58-4cd7-9555-be2851dd38cb Tenant ID: bbd5ea6b-fed5-40a7-8327-85f0aedaa4e5

Feature flags requiring approval:

1. Microsoft.Network/AllowNetworkSecurityPerimeter — State: Pending
2. Microsoft.Network/EnableServiceTagsInNsp — State: Pending

Could you please approve these two preview feature registrations for the subscription above, so we can proceed with configuring Service-tag-based inbound access rules on our Network Security Perimeter?

Please let us know if any additional information is required.
