Dear Vivek,
Agree with you.
I can only find home page from google about the same.
But few of its links are broken.
Check this one: (Its having few broken links as well )
Early Access Program: ML Builder | OutSystems
As the name suggests, its early access and now I believe no longer available for early access.
Its currently providing early access program for Project Neo when I am trying to register in EAP.
Kindly try to submit your feedback with little chat icon on right side of screen. It might expedite the process.

Regards,
Palak Patel
