Add category name to body classes

Hi,

It seems that the dropdowm menu I choose the categories from when I edit an article as been implemented with ACF.
It would explain why the solution I saw everywhere to add the category name in the body classes does not work for me. It does nothing.
I am talking about this one there to put in function.php :

add_filter('body_class','add_category_to_single');
  function add_category_to_single($classes) {
    if (is_single() ) {
      global $post;
      foreach((get_the_category($post->ID)) as $category) {
        // add category slug to the $classes array
        $classes[] = $category->category_nicename;
      }
    }
    // return the $classes array
    return $classes;
  }

So I guess there is a way to achieve that with a different code assuming this category dropdown was implemented with ACF.

I’d be really happy if you can help me for this first ever question I ask here ?

I thought I should add more details.
Here are my investigations :
There is a screen capture of my post edition page attached.
I found a json file in my theme that seems to deal with categories in an ACF-jon folder :

{
    "key": "group_5ac5d1e87ab94",
    "title": "Categorie",
    "fields": [
        {
            "key": "field_5ad704be7333f",
            "label": "Afficher la catégorie courante",
            "name": "afficher_les_articles_dans_la_page_categorie",
            "type": "true_false",
            "instructions": "",
            "required": 0,
            "conditional_logic": 0,
            "wrapper": {
                "width": "",
                "class": "",
                "id": ""
            },
            "message": "",
            "default_value": 1,
            "ui": 1,
            "ui_on_text": "",
            "ui_off_text": ""
        }
    ],
    "location": [
        [
            {
                "param": "taxonomy",
                "operator": "==",
                "value": "categorie"
            }
        ]
    ],
    "menu_order": 0,
    "position": "normal",
    "style": "default",
    "label_placement": "top",
    "instruction_placement": "label",
    "hide_on_screen": "",
    "active": 1,
    "description": "",
    "modified": 1530175641
}

And finally that’s what I tried to add in function.php with no success :

add_filter('body_class', 'add_acf_body_class');
 
function add_acf_body_class($class) {
    $value = get_field('afficher_les_articles_dans_la_page_categorie', false, false);
    $class[] = $value; 
    return $class;
}
