Get custom field from a custom post throught a custom fields with ACF

Question

The goal is to create a custom post (intervenant) with custom fields (job / image). (done)

Select this object in Post (done)

and display the content in a shortcode (in progress)

I did this Loom to show you what I did. The result in intervenant (The two picture with the lorem ipsum) is static for now.

This my code now, I only see the name and content of the custom post and no custom field 'job' or 'image' :

add_shortcode('display_acf_image', 'acf_image');
function acf_image() {

// HERE : HTML CSS PHP to display the content of the custom post.

    $intervenant = get_field('intervenant');
    debug($post); //print

    if( $intervenant ): ?>
        <h3><?php echo esc_html( $intervenant->post_title ); ?></h3>
        <?php foreach( $intervenant as $post ):

            setup_postdata($post); ?>
            <h4><?php the_field( 'job' ); ?></h4>
        <?php endforeach; ?>
    <?php endif;

}

My code should work like this ?

This is the print_r of intervenant :

WP_Post Object

    [ID] => 637

Thx

EDIT1 : It's a beautiful print :)

function debug($print)
{
    ?>
    <pre><?php
    print_r($print);
    ?></pre><?php
}

I find the way to do it :

add_shortcode('display_acf_image', 'acf_image');
function acf_image()
{
    $intervenant = get_field('intervenant');

        if( $intervenant ):
            global $post;

            foreach( $intervenant as $post ):
               setup_postdata($post);

               $name = get_field( 'name' );

               <span><?= $name ?></span>

        endforeach;

        endif;



}

I use setup_postdata() to have access to the custom post and custom fields of it.
