How can custom fields be displayed on the Profile page

Hi!
I'm trying to customize the profile page layout in EasySocial. I need to display several custom fields on the profile page (except those which are displayed there by default).
But I'm struggling to find out how any custom field can be rendered on a page. Tried to edit 'default.header.php' file with no success.
Please advice.
Hope, the best support team can easily help with this

Thank you!
