Catch the submission event on my gorgias contact form to push event on dataLayer

Hi everyone,

I’m trying to catch the submission event on my gorgias contact form, embedded on my Shopify store, to collect it on my tag manager.

I couldn’t get the event directly via GTM and I’m struggling to get it via JS.

Do you know if there is a way to do that? I asked to Gorgias support but they told me to ask here for help.

Thanks in advance.
