User Selection for Order

I am assigning a manager to an order with the code below. But I do this with manual IDs. What I want to do is "wp_dropdown_users(['role' => 'shop_manager']);" To make a selection with dropdown. How should I go about this.

    woocommerce_wp_select( array(
        'id' => '_store_manager_id',
        'label' => 'Manager:',
        'value' => $manager,
        'options' => array(
            '1' => 'Manager 1',
            '2' => 'Manager 2',
            '3' => 'Manager 3'
        ),
        'wrapper_class' => 'form-field-wide'
    ) );


add_action( 'woocommerce_process_shop_order_meta', 'manager_save' );

function manager_save( $order_id ){

    update_post_meta( $order_id, '_store_manager_id', wc_clean( $_POST[ '_store_manager_id' ] ) );
    // wc_clean() and wc_sanitize_textarea() are WooCommerce sanitization functions
    
}
