Author Profile Pages

I am trying to add custom field information to my author pages like https://www.obsessedwithfilm.com/author/hitmanuk2k/

I have installed the https://www.cimatti.it/blog/cimy-wordpress-plugins/cimy-user-extra-fields/

But how can I add these fields to my author.php page template which I have set up? I have looked through every part of the readme but it’s no use, it only covers usage within the loop. The author pages are not in the loop.

Alternatively is there a simple way of adding extra fields to the default ‘Profile’ page, as I have been succesful in adding the things like AIM and Jabber to my author pages.
