How to understand and make use of Puppet modules and their descriptions in Foreman?

Problem:
(Not sure if it belongs here or in Tutorials) I’m still super-fresh into all this Foreman/Puppet business; have Ubuntu Server 18.04 with Foreman/Puppet setup, few test clients (ubuntu/linux mint) running agents. I want to update sudoers file (or sudoers.d directory, whatever works) on clients by adding some Active Directory group to it (clients are joined to domain through sssd/realmd). Basically I need to write down this thing in specific place (and avoid to nullify original file if possible):
%Role-Linux-Sudoers ALL=(ALL:ALL) ALL

I’ve downloaded and installed module for puppet “saz/sudo” which supposedly should give me such control. Now I’m staring in Readme page and trying to figure out how to translate something like this:
sudo::conf { 'admins': priority => 10, content => '%admins ALL=(ALL) NOPASSWD: ALL', }
into “fill and click” configuration for module in Foreman.

Should I go and override something in “configs” section of Smart Class Parameter or has it something to do with sudo::params class which don’t have Smart Class Parameter at all… I just don’t understand how to make sense out of it.

Expected outcome:
How exactly to read those puppet modules readme syntax and get out of it something useful in Foreman? Could someone please explain?
