How to get the top user list?

I’m using this wonderful plugin.
I am working on making a top user list but it is hard to find any helpful information here.
I tried to use ;

$user_args = array(
'ap_query' => true,
'role__not_in' => [ 'administrator', 'ap_moderator' ], 
'number' => 7,

but, it gives me only 7 users which was registered recently.
Is there anyway, I can get the list by filtering this list with reputation point?
Thank you.
