I am new to Wagtail and I am trying to work out how to extract the query string as part of the FormPage model.

In models.py I tried:

def get_context(self, request):
        context = super().get_context(request)
        context['embed'] = request.GET.get('embed')
        return context

But I’m not 100% how to call this in my FormPage model to include this in the email that will be sent when a form is submitted.

I’ve tried to add the following to the FormPage model:

def get_context(self, request):
        context = super().get_context(request)
        context['embed'] = request.GET.get('embed')
        return context
