[Theme: Customizr] Different header regarding page

Hello,

I am trying to load a different header on my homepage, from the other pages, with the theme Customizr (v.3.3.19).

I’ve created a child theme and a new header: header-home.php

I know I have then to change this :

<?php get_header(); ?>

By:

<?php
if ( is_home() ) :
	get_header( 'home' );
else :
	get_header();
endif;
?>

However, the template doesn’t contain this line. I’ve only found the following hook in the file “inc/parts/class-header-header_main.php”

add_action ( '__before_main_wrapper'	, 'get_header');

Any lead would be very appreciated.

Thanks,

Chris
