How can I output a group field for current users

I'm trying to retrieve my group field that I've added to the user profile with the user meta Addon, I'm trying to adapt output code that I've used before from a page meta but it's not working for user meta.

Please see my code below:

User Metabox:

<?php
add_filter( 'rwmb_meta_boxes', 'am_dz_statement_metabox' );

function am_dz_statement_metabox( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'  => __( 'Statements', 'your-text-domain' ),
        'id'     => 'statements',
        'type'   => 'user',
        'fields' => [
            [
                'name'        => __( 'Statements', 'your-text-domain' ),
                'id'          => $prefix . 'am_statements',
                'type'        => 'group',
                'collapsible' => true,
                'clone'       => true,
                'sort_clone'  => true,
                'fields'      => [
                    [
                        'name' => __( 'Statememnt File', 'your-text-domain' ),
                        'id'   => $prefix . 'AM_statment_file',
                        'type' => 'file_advanced',
                    ],
                    [
                        'name' => __( 'Statement Title', 'your-text-domain' ),
                        'id'   => $prefix . 'AM_statement_title',
                        'type' => 'text',
                    ],
                ],
            ],
        ],
    ];

    return $meta_boxes;
}

Shortcode:

<?php
add_shortcode('am_dz_statements', function() {

    $statements = rwmb_meta( 'statements', ['object_type' => 'user'], $user_id );//Slides needs to be var in the module
    if ( empty( $statememnts ) ) {
        return '';
    }
    if ( ! empty( $group_values ) ) {
    foreach ( $group_values as $group_value ) {
        $value = isset( $group_value[$sub_field_key] ) ? $group_value[$sub_field_key] : '';
        echo $value; // Display sub-field value
    }
    }
    $counter = 0;
        foreach ( $statements as $statement ) {
            $counter++;
            $statementfile = $statement['AM_statment_file'];
            $statementtitele = $statement['AM_statement_title'];
            
            $output .= '<div id="am-statement-' . $counter .'" class="am-statement">';
            
            $output .= '<h2 class="fm-slide-title">';
            $output .= '<a href="' .  . '">' . $statementtitele . '</a>';
            $output .= '</h2>';
           
            $output .= '</div>';
            
        }
        return $output;
} );
