The option to add a Google Tag Manager script in the form

We see there is a Google Analytics widget but need to deploy GTM on a form.

I'm sorry, but there is no option you can have a Google Tag Manager script in our form builder. There is a widget, but it is currently under development. 

I have raised this thread to our backend team as a feature request. We cannot provide you a timeframe for the request, but as soon as we have an update, you will be notified here. 

In the meantime, you may consider placing the script on your website where the form is embedded.
