I am trying to create a shortcode that will list posts from a custom post type. I remember reading somewhere that with piklist I can create features that piklist doesn’t support using the same code as a non-piklist plugin. I have tried doing this but whenever I use a shortcode, it just shows the shortcode, nothing is rendered. I have my main function code below.

<?php
/*
Plugin Name: MBA Membership
Plugin URI: https://accessdrive.net/
Description: Custom plugin designed for the Mississippi Beekeepers Association for managing their members.
Version: 1.0
Author: Michael Smith (Accessdrive)
Author URI: https://accessdrive.net/
Plugin Type: Piklist

add_action('init', 'my_init_function');

function my_init_function()
{
  if(is_admin())
  {
   include_once('pc.php');
 
   if (!piklist_checker::check(__FILE__))
   {
     return;
   }

   //Set Filter and Actions for Plugin
   add_filter('piklist_admin_pages', 'mba_member_settings');
   add_filter('piklist_post_types', 'mba_member_data_cpt');
   add_action('init', 'mba_list_members_shortcode');
   
  }
}

function mba_member_settings($pages){
 
      $pages[] = array(
        'page_title' => 'MBA Membership Settings'
        ,'menu_title' =>  'Membership Settings'
        ,'sub_menu' => 'options-general.php'

      );
   
      return $pages;
    
  }
