ACF how to get categorie taxonomy image to display inside grid - image

Question

I have a classifieds site created with Wordpress and ACF, I created a Custom Post CLASSIFIEDS and a Taxonomy named "Main Category". I added in "Main Category" the various categories concerning the classifieds (Real esate, Job,...).
I created with ACF a field "Image Category" that I assigned to the "Main Category" Taxonomy, so I can add an image to each of the Princiaples Categories. My goal is to be able to display a grid with my different ads and to display the image of the main category in each ad card.
So I tried with function inside my functions.php :
function render_custom_field_image_block() {
// Object can be a post, term or user.
$object = wpgb_get_object();
echo ("VALUE :");
var_dump($object);
// If this is not a post (you may change this condition for user or term).
if ( ! isset( $object->post_type ) ) {
return;
}
// categorie_image is the field name about my category image field created with ACF
$image_id = get_post_meta( $object->ID, 'categorie_image', true );
if ( empty( $image_id ) ) {
return;
}
// You can change the image size "medium_large" to suit your needs.
$image_url = wp_get_attachment_image_url( $image_id, 'medium_large' );
if ( empty( $image_url ) ) {
return;
}
printf(
'<img src="%s" alt="%s" width="100%" height="250px" style="object-fit:contain">',
esc_url( $image_url ),
esc_attr( get_post_meta( $image_id, '_wp_attachment_image_alt', true ) )
);
}
But not working and the var_dump on $object don't contain info about categorie image except the ID of the categorie :

So my question is how to get the URL of the categorie_image?
