Tenant Allow/Block Lists not working as expected

The following is stated on Microsoft's docs related to adding an allow entry in a tenant's Allow/Block lists:

When you submit a blocked message as I've confirmed it's clean and then select Allow this message, an allow entry for the sender is added to the Domains & email addresses tab on the Tenant Allow/Block Lists page.
ref: https://learn.microsoft.com/en-us/defender-office-365/tenant-allow-block-list-email-spoof-configure#create-allow-entries-for-domains-and-email-addresses

I've been submitting quarantined messages for a while now with the specified verdict, both directly from quarantine queue while also using https://security.microsoft.com/reportsubmission .

Either way, none of these result in an email address allow entry to be added in Tenant Allow list page.

What am I missing?
