We hope you are doing well! I just wanted to reach out as we are having difficulty creating conversion events around the give butter lead/email subscription forms (for example, the form at the bottom of this page) and were curious as to if your team had any insights around possibilities. Currently, we are able to measure donations via givebutter iframes by using an event handler to push a datalayer event to our tag management system where we can then forward events. It seems that we are unable to do this with the lead form. Is there any option to be able to do this or any additional workarounds that your team might be aware of? Another piece of context that might be helpful is that the only postMessage event I'm seeing pushed from the event listener to the data layer is givebutter-form-loaded. We'd like to see if there is a way to push an embedded form completion event, as Givebutter has done with its embedded donation form using the postMessage event givebutter-complete.
