Avia Page Builder and Custom Post type

Hi, again
While I was waiting for your answer, I tried to investigate a bit more to find the solution to my “advanced fieds not displaying” problem.
I found out that to display these advanced custom fields, I needed to insert more code in the single.php file. This is the code:
<div class=”infos-service”>

• Collectivités : <?php the_field(‘collectivites’); ?>
• Adresse : <?php the_field(‘adresse’); ?>
• Téléphone : <?php the_field(‘telephone’); ?>
• Courriel : <?php the_field(‘courriel’); ?>
• Services et prestations : <?php the_field(‘services-et-prestations’); ?>
• Missions autres que documentaires : <?php the_field(missions-autres-que-documentaires’); ?>
• Rattachement hiérarchique : <?php the_field(‘rattachement-hierarchique’); ?>
• Nombre de personnes dans le service : <?php the_field(‘nombre-de-personnes-dans-le-service’); ?>
• Logiciel documentaire utilisé : <?php the_field(‘logiciel-documentaire-utilise’); ?>

</div>

I now have 2 questions:
– I’m supposed to insert these lines in the single.php file but there is no such file in the Enfold Child Theme larger file. Should I insert these code lines in the regular Enfold file?
– if so, my documentation (https://kinsta.com/blog/advanced-custom-fields/#display) tells me I should paste below the entry-content section… which does not exist in the Enfold single.php file. I’m pasting the whole file below, could you tell me where I need to paste the new code lines? Thanks in advance!

<?php
if( ! defined( ‘ABSPATH’ ) ) { die(); }

global $avia_config;

/*
* get_header is a basic wordpress function, used to retrieve the header.php file in your theme directory.
*/
get_header();

$title = __(‘Blog – Latest News’, ‘avia_framework’); //default blog title
$t_link = home_url(‘/’);
$t_sub = ”;

if( avia_get_option( ‘frontpage’ ) && $new = avia_get_option( ‘blogpage’ ) )
{
$title = get_the_title( $new ); //if the blog is attached to a page use this title
$t_link = get_permalink( $new );
$t_sub = avia_post_meta( $new, ‘subttenitle’ );
}

if( get_post_meta( get_the_ID(), ‘header’, true ) != ‘no’ )
{
echo avia_title( array( ‘heading’ => ‘strong’, ‘title’ => $title, ‘link’ => $t_link, ‘subtitle’ => $t_sub ) );
