title: Docusign API receiving status of optional sign here tab
body: <p>I am using Docusign API (PHP) to request a signature by email using a PDF File. Inside the PDF are 2 sign_tabs/anchors and one is optional. I need information after completion if the optional sign_tab was signed. How do I get this information? Wether the  EnvelopeFormData::get or the envelope info via  Envelopes::get provide any info about the sign_tabs itself...</p>
  <p>Here is how I implemented the tabs:</p>
  <pre><code>$sign_here = new SignHere(['anchor_string' =&gt; '/sign_here/',]);
  
  $sign_here_optional = new SignHere(
  ['anchor_string' =&gt;'/sign_here_direct_debit_mandate/',
  'optional'      =&gt; TRUE,]);
  </code></pre>
  <p>Thank you.</p>
