Retaining a domain registered during a GSuite Admin course

[Ditto]

I registered a domain with domaindiscount24 through google as part of a GSuite Admin course. The course is now finished and I no longer have access to the Google Admin console. The course provided free access to a full enterprise GSuite account for a few weeks, but I'd rather not setup a full subscription at this point just to retain the domain name. I registered for one year without auto renewal, but would now like to keep the domain. I'm unclear how I can renew the domain in this case. Any suggestions?

Can you do a login / do a password reset on the domaindiscount24 website?

Not that I can recall - have tried my usual options. I have a feeling that you log in in via the console on a randomly generated password at the time.
