Hello Renan,

You can add the following PHP code snippet to your site to remove the various options and buttons that allow the agent to edit the order:

add_action('admin_head', function(){
    if (is_agent(get_current_user_id())){
        ?>
        <style>
            #woocommerce-order-actions, .edit_address, .add-items{
                display: none !important;
            }
        </style>
        <script>
            jQuery(document).ready(function(){
                jQuery('#woocommerce-order-actions, .edit_address, .add-items').remove();
            });
        </script>
        <?php
    }
});
function is_agent($user_id){
    $agent_group = get_user_meta($user_id,'salesking_group',true);
    if ($agent_group !== 'none' && !empty($agent_group)){
        return true;
    } else {
        return false;
    }
}

This snippet can be added to functions.php, or by following our guide here: https://woocommerce-b2b-plugin.com/docs/how-to-add-a-snippet-php-or-js/

Let me know if you need anything else, any button or area there to be removed, and I can adjust the snippet for that,

Kind regards,

Stefan
