Getting child theme updates via FTP to work

I am trying to make changes to the class-breadcrumb.php file via FTP (using FileZilla). I downloaded the class-breadcrumbs.php file from the parent theme folder, made the following changes:

‘show_home’ => __( ‘Home’, ‘avia_framework’ ),

to

‘show_home’ => __( ‘Core Sensors’, ‘avia_framework’ ),

Basically changing the word “Home” on the breadcrumbs trail to the company name of the website.

I then re-upoaded the new file to my Enfold-child folder with the same name as the parent folder. My understanding was that this would then tell the child theme to override the parent theme. However, went i do the upload, clear any cache from the website, the changes I made are not showing.

I checked in my functions.php file in my child theme and noticed there are no enqueue hooks (correct terminology?) to the parent theme. Mine only shows the following:

<?php
// Exit if accessed directly
if ( !defined( ‘ABSPATH’ ) ) exit;

// BEGIN ENQUEUE PARENT ACTION
// AUTO GENERATED – Do not modify or remove comment markers above or below:

// END ENQUEUE PARENT ACTION
if ( is_home() ) {
remove_action( ‘woocommerce_before_main_content’, ‘woocommerce_breadcrumb’, 10, 0);
}

Am I missing something in my functions.php file to make the files in my child theme active.
