title: Get chosen shipping method title by its Id in WooCommerce
body: <p>In WooCommerce <code>includes\class-express-checkout-gateway.php</code> file I am getting shipping method Id by the following code:</p>
  
  <pre><code>$chosen_shipping_methods = WC()-&gt;session-&gt;get('chosen_shipping_methods');
  </code></pre>
  
  <p>It gets <code>flat_rate:1</code>, but I need its title - <code>Flat Rate</code>.</p>
  
  <p>I have already tried all this <a href="https://stackoverflow.com/questions/26126438/how-can-i-access-current-woocommerce-order-shipping-method-id">answers</a> and many more.</p>
  
  <p>How can I get this?</p>
