Is zoho developer custom solutions platform available at the moment?

Greetings

I've read the zoho developer custom solutions documentation in length and i've found this statement: "Due to an overwhelming number of signups, the Custom Solutions beta is temporarily closed for new signups from 19th June 2020. However, existing solutions will continue to work."
is this service still closed to this day? because i can't find it anywhere right now on zoho developer.

Thanks.
