Get Shipping Zone Method

I’m trying to display the customers shipping zone’s name, ID and method e.g. Flat Rate.

Then do an IF statement on those answers, I can do everything except for “get the method ID” as it always errors;

Uncaught Error: Call to undefined method WC_Shipping_Zone::get_method_id()

I’ve checked and it seems to be correct method term so not sure why nothing is returning…

function woo_wc_minimum_order_amount() {
      
    $minimum = 20; // change this to your minimum order amount

    // Get cart shipping packages
    $shipping_packages =  WC()->cart->get_shipping_packages();

    // Get the WC_Shipping_Zones instance object for the first package
    $shipping_zone = wc_get_shipping_zone( reset( $shipping_packages ) );

    $zone_id   = $shipping_zone->get_id(); // Get the zone ID
    $zone_name = $shipping_zone->get_zone_name(); // Get the zone name
    $zone_method = $shipping_zone->get_method_id(); // The shipping method slug

    // Testing output
    echo '<p>Zone id: ' . $zone_id . ' | Zone name: ' . $zone_name . ' | Zone name: ' . $zone_method . '</p>';

  
    if ( WC()->cart->subtotal < $minimum ) {
  
        if ( is_cart() ) {
  
            wc_print_notice( 
                sprintf( 'You must have a minimum order amount of %s to place your order. Your current order total is %s.' , wc_price( $minimum ), wc_price( WC()->cart->subtotal ) ), 'error' );

            remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );
  
        } else {
  
            wc_add_notice( 
                sprintf( 'You must have a minimum order amount of %s to place your order. Your current order total is %s.' , wc_price( $minimum ), wc_price( WC()->cart->subtotal ) ), 'error' );

            remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );
  
        }
 
    }
  
}
