Legacy License Key

We recived a license mail which says:

How to use your new key
If you’re using version 2025.1 or later: You can use the new universal key across all products and solution packages.
If you’re still on a version prior to 2025.1: You’ll need to use your legacy license key instead. Log in to the Devolutions Portal to access it.

When I access the portal, I am able to see our universal license, but no where to get the legacy key. How to proceed? We are currently using RDM in Version 2023.1.29.0 64-bit and are not able to upgrade currently.
