How to use BETA repos

Yesterday I wanted to look into Red Hat's Certificate System and figured I install the BETA version using my Red Hat BETA subscription.

Following the install guide for Certificate System I attached the BETA pool to my server (running 8.7) and following the information in the subscription portal to determine the repo name I tried to enable the required repos:

subscription-manager repos --enable dirsrv-beta-for-rhel-8-x86_64-rpms --enable certsys-beta-for-rhel-8-x86_64-rpms

This however just prompted an error saying:
Error: 'dirsrv-beta-for-rhel-8-x86_64-rpms' does not match a valid repository ID. Use "subscription-manager repos --list" to see valid repositories.
Error: 'certsys-beta-for-rhel-8-x86_64-rpms' does not match a valid repository ID. Use "subscription-manager repos --list" to see valid repositories.

repos --list just show a couple of repos which seems to be just a subset of the repos that should be in the BETA access subscription.

I have tried searching both the reguler red hat site and the developer site but have not found anything that seems to address this issue (including refreshing/unregister/register/clean/remove etc).

Is there a step I'm missing here, do I need to do something more than just attaching the pool (the customer portal - subscription page shows no errors for this system)>

any help would be appreciated.
