Your inital code says we can do it via arguments in erp\includes\functions-people.php

$defaults = [
        'type'       => 'all',
        'number'     => 20,
        'offset'     => 0,
        'orderby'    => 'id',
        'order'      => 'DESC',
        'trashed'    => false,
        'meta_query' => [],
        'count'      => false,
        'life_stage' => '',
        'include'    => [],
        'exclude'    => [],
        's'          => '',
        'no_object'  => false
    ];

Can u give an example with what i wish to achieve using $defaults or any example that is closer and works with multiple meta values?
