Adding different sidebar to a template

I am using the Epik theme from Genesis
https://development.fers-route-to-retirement.com/free-articles/

The theme comes with a primary (right) and secondary (left) sidebar but I want to create a template page for a certain section of the site that just has a secondary sidebar.

1. I created a template – page_lessons.php

2. I registered a new sidebar widget in the child functions file using this code:

//* Register lessons sidebar widget area
genesis_register_sidebar( array(
	'id'            => 'lessons',
	'name'          => __( 'Lessons Page', 'Epik' ),
	'description'   => __( 'This is a sidebar widget area for the lessons pages', 'Epik' ),
) );

3. I created a new sidebar_lessons.php file and put this in it:

<div id="sidebar" class="sidebar widget-area">
<?php
    genesis_structural_wrap( 'sidebar' );
    do_action( 'genesis_before_sidebar_widget_area' );
    dynamic_sidebar('lessons-sidebar');
    do_action( 'genesis_after_sidebar_widget_area' );
    genesis_structural_wrap( 'sidebar', 'close' );
?>
</div>

4. This is where I think I went wrong:
I added this code to the page_lessons.php file:

<?php
// Template Name: Lessons
//* Hook after post widget area before page content
genesis_widget_area( 'after-post', array( 'before' => '<div class="after-post widget-area">',

add_action( 'get_header', 'child_sidebar_logic' );
/**
 * Swap in a different sidebar instead of the default sidebar.
 *

 */
function child_sidebar_logic() {
    if ( is_page_template( 'page_lessons.php' )  )
	{
        remove_action( 'genesis_before_sidebar_widget_area', 'genesis_get_sidebar' );
        add_action( 'genesis_before_sidebar_widget_area', 'child_get_lessons-sidebar' );
    }
	{
        remove_action( 'genesis_after_content', 'genesis_get_sidebar' );
         }
}
/**
 * Retrieve blog sidebar
 */
function child_get_lessons() {
    get_sidebar( 'lessons-sidebar' );
}
genesis();

5. On the page I am using to test it, it is still showing the regular secondary sidebar from the original sidebar widget. It did remove the primary sidebar, as I wanted, but the content area is still as narrow as though there is a sidebar there. I get confused about naming conventions with this stuff – is that my problem? Or is there something else wrong?
