I think that having the email address be at the top of both the 'help' and 'feedback & community' links (to their respective help pages) at the footer of the kagi site is already doing enough to make the emailadres visible.
All that needs to happen here is have the 'contact support' link show you the emailadress IF you don't have a mailto configured (not sure if that's a thing that can be done). If that's not possible then that link should probably also just link to https://help.kagi.com/kagi/ or something

A support form could also be a thing I suppose but I'm not sure what the benefit would be over just listing the emailadress?
