How to set up a bitrix24 chat target in Yandex.Metrica via GTM?

Question

Yandex.Metrica

We really need your help!
I've been trying for two days now, nothing happens.
We set up tracking the goal of the Bitrix24 chat via GTM (to Metrica) following this instruction: xn--80ajr5b.com/2018/06/metrika-bitrix24-onlinechat/, but the goal is still not collected.
Here are the screenshots:





What went wrong and can be corrected?

Answer 1

Have you found out at what stage you have a problem?
Does the event arrive in the metric? Does the tag work in GTM? And the trigger?

Answer 2

Roman , the event does not arrive in the metric. I don't know how to understand if the trigger and tag work in GTM.

Answer 3

It may be useful to someone:
1) In GTM, create a tag that will send an event that a chat has been started, with the code

<script>
window.addEventListener('onBitrixLiveChat', function(event)
{
  var widget = event.detail.widget;
  widget.subscribe({
    type: BX.LiveChatWidget.SubscriptionType.sessionStart,
    callback: function(data) {
    	dataLayer.push({"event": "b24_chat_start"});
    }
  });
});
</script>

Activation trigger on all pages
2) We hang tags in GTM with targets on the trigger with the event b24_chat_start
