Webflow ecommerce events to segment

Hey There

I am tracking users using segment.io.
I would like to add a track event to the order confirmation page which passes
-Customer email
-Itemslist
to segment. I am not able to find any list of variables that webflow uses. Since they are also passing all these info to GA the variables must be there.

the track push would look like this:

analytics.track(‘Success’ ,{
email: xxxx??,
orderItems: xxxxx??
});

I can extract the email out of the div-container. But that is not very sustainable. These vars must be defined already somewhere.

Any ideas?
Thanks
Philippe
