Tracking form submission for multiple forms on a page

Hi, I’ve inherited a site that has multiple CF7 forms on one page and there’s a requirement to track the submission event of each form separately.

Having looked at this post on the CF7 site (https://contactform7.com/tracking-form-submissions-with-google-analytics/) I can see how to track a single form but how would I amend the function so the correct form submission event is recorded?

Many thanks.
