SIGNER_COMPLETE event does not get received by addEventListener

I use the event notifier with a Iframe (https://community.onespan.com/documentation/onespan-sign/codeshare/esignlive-event-notifier) for couple years in my projet and when I have configure it initially the event to check for completion was ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE.

I don't know if there has been a change in the event because i'm not receving ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE anymore and I receive ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE_REVIEWED for the last message after signature.

What is the difference and impact?

Do I need to process the ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE_REVIEWED message?

Do I use a wrong configuration that cause this behavior?

That was my code from the iframe event -> 

OLD VERSION

    window.addEventListener('message', receiveMessage, false);

    function receiveMessage(event) {

      var origin = event.origin || event.originalEvent.origin;

      var data = event.data;

      console.log(data, origin);

      switch (data) {

      case 'ESL:MESSAGE:ERROR:SESSION_EXPIRE':

        console.log("Session expired");

        window.location.replace("<%= ViewData["SiteParticipantLogin"] %>");

        break;

      case 'ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE':

        $("#my_iframe").hide();

        $("#boutonRetour").hide();

        event.source.postMessage('ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE', origin);

        window.location.href = "<%= ViewData["SiteParticipantAccueil"] %>";

        break;

      case 'ESL:MESSAGE:REGISTER':

        console.log("REGISTER");

        event.source.postMessage('ESL:MESSAGE:ACTIVATE_EVENTS', origin);

        break;    

      default:

        console.log(event);

        event.source.postMessage(data, origin);

        break;

      }

    }

        window.location.replace("<%= ViewData["SiteParticipantLogin"] %>");
        break;

      case 'ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE':
        $("#my_iframe").hide(); 
        $("#boutonRetour").hide();
        event.source.postMessage('ESL:MESSAGE:SUCCESS:SIGNER_COMPLETE', origin);
        
        window.location.href = url;
          break;
