I am embedding a form into a web app, and for security reasons cannot use 3rd-party cookies.

I’m gathering feedback from users of the app, and once they’ve seen the form -- either filled it out or closed it -- I don’t want to show it to them again.

How can I tell when a user has completed/viewed a form? Does the submission/closing action do anything that I can append a listener to?

The only thing I can think is to watch the “data-tf-loaded” attribute on the embed div. If it changes, then that’s as good an indicator as I’m going to get, then I can save a flag to my user’s account that they’ve filled out the form.

Any insight would be appreciated.
