Add Leads from GoTo Webinar to Active Campaign


I am trying to get leads / attendees from GoTo into Active Campaign. This means every time someone registers for a webinar, I want the contact data synced to Actice Campaign.
But in the first step, when this happens..., i cannot choose GoTo Webinar. It does not appear in the list.
It can be chosen in step 2, do this.... But i want to start when a new registration is made in GoTo webinar.

How can I do this?
