title: Change WooCommerce phone number link on emails
body: <p>I need WooCommerce email phone number to open Whatsapp on click. Currently when I click on it, it opens option to dial the number, I want to change this to open to Whatsapp.</p>
  <p>So far I've found is (last option).</p>
  <pre><code>&lt;?php
      function wc_make_phone_clickable( $phone ) {
          $number = trim( preg_replace( '/[^\d|\+]/', '', $phone ) );
          return $number ? '&lt;a href=&quot;tel:' . esc_attr( $number ) . '&quot;&gt;' . esc_html( $phone ) . '&lt;/a&gt;' : '';
      }
  ?&gt;
  </code></pre>
  <p>I will really like not to touch the plugin since upon updates this will be lost.</p>
  <p>Whatsapp link  <a href="https://wa.me/1XXXXXXXXXX" rel="nofollow noreferrer">https://wa.me/1XXXXXXXXXX</a>, but phone field on checkout page does not have area code, so i will need to add this to</p>
