dataLayer events not showing up inside Google Tag Manager

Hi, we are using native typeform integration, but it seems like the integration blocks the communication between the dataLayer object and Google TagManager.

GTM cant see any events dispatched.

When debugging GTM, all GTM events happen normally, but every time we need to use dataLayer, GTM cant see it.

Thats the url:

When we run this js command in the console

dataLayer.push({'event': 'formSent', 'testData':'testData'});

We should see the event inside GTM debugger, but nothing happens.
