Swagger Definition of Infusionsoft API

I am looking for a Swagger definition of the Infusionsoft API that is used to generate this documention: https://developer.infusionsoft.com/docs/rest/

In another post I read that “you can get the Swagger doc that generates that documentation from any Infusionsoft application at the /app/v2/api-docs subresource”

I have not been able to get that to work, what would the first part of that URL be?

Resolved in another thread.
