Server 2025 to server 2022 downgrade keys

Hello,

We bought licenses with these part #'s MFR# P73-08495 and MFR# EP2-25187 which, according to searches on the internet, have downgrade rights.

We need to get downgrade keys for server 2022 standard.

Our reseller referred us to Microsoft for this.

Could someone help? The activation portal does not give us an option to do this and a microsoft support agent told us to make a post here which seems weird to us. We don't know why they couldn't help us via the phone.

Thanks
