Zoho Recruit PRO Edition subscription problem

I've paid for Zoho One - and want subscribe to a Recruit PRO account.

My organization, at the moment, has two paid users ... and my account is the only account that has logged in, and I want my account to be the recruiter for the company

I've successfully uploaded a job description - https://bit.ly/3HCiHFz - and I've published it to the free job boards.

And I understand that once I subscribe to Recruit Pro then I can upload the job description to the other boards too.

I can't figure out how to actually subscribe to PRO. I've searched all over the Recruit How do I do that?
