Hide Subscriber Users from BuddyPress member Directory

hide-subscribers.php

add_action('bp_ajax_querystring','bpdev_exclude_users',20,2);
function bpdev_exclude_users($qs=false,$object=false){
    //list of users to exclude
     
    if($object!='members')//hide for members only
        return $qs;
        
    $excluded_user=join(',',bpdev_get_subscriber_user_ids());//comma separated ids of users whom you want to exclude
  
    
    $args=wp_parse_args($qs);
    
    //check if we are searching for friends list etc?, do not exclude in this case
    if(!empty($args['user_id']))
        return $qs;
    
    if(!empty($args['exclude']))
        $args['exclude']=$args['exclude'].','.$excluded_user;
    else 
        $args['exclude']=$excluded_user;
      
    $qs=build_query($args);
   
   
   return $qs;
    
}

function bpdev_get_subscriber_user_ids(){
  
    $subscribers= get_users( array( 'role' => 'subscriber', 'fields' => 'ID' ) );
  
   return $users;
}

Has anyone made this work by hiding users based on Paid Memberships Pro level?

Ex: hide users with membership level 1,2,3 from BuddyPress Member Directory

Would anyone be able to help me with modifying this code so that all user roles are hidden, except for users with a specified user role?

Super late reply, but for @Hastibe and anyone else who wants to exclude all but one role, change the exclude to include.

// Helper for fetching all IDs to include. Returns an array in this example.
$included_user_ids = my_function_to_fetch_all_users_by_role();

$args = wp_parse_args( $qs );
$args['include'] = implode( ',', $included_user_ids );

$qs = build_query( $args );
