How to find the correct path to renew my XERO certification?

XERO is emailing me for 2 months that your XERO certification will expire in Sep 26 (third week), but on reaching to XERO central (where the path shown in the email takes to), I can see my certification and the expiry date, but not the link to renew it.

Unlike QBO, they don't seem to have a well-defined renewal path (however, I enjoy working on XERO software much more than QBO).

Can't somebody throw some light on it?
