title: How can I add multiple inputs to a SweetAlert2 popup?
body: <p>I have code on my website that uses a SweetAlert2 popup to let users request songs:</p>
  
  <pre><code>$('#request-song').click(async function() {
    const { value: song } = await swal({
      title: "Request a Song (please note song request won't be played unless we are live)",
      input: 'text',
      inputPlaceholder: 'Enter Artist - Song Name',
    });
  
    if (song) {
      $.post("functions/request.php", {request: song}, function(data) {
        console.log(data);
      });
      swal({type: 'success', title: 'Success!'});
    }
  });
  </code></pre>
  
  <p>But when I add another input it will only read the second one. How do I add another input so listeners can include their name/username for shoutouts?</p>
