Changing Make module to consume new data from API

I have a complex Make scenario that consumes events from the Stripe API.

I have to make some changes to how it interacts with Stripe API to better handle some specific subscription edge cases in our app.

My problem is that when I open my Make scenario to edit it, I can only see and work with the Stripe API data and values that are associated with the most recent Stripe API event that the module has received.

Stripe API issues many different kinds of events, each with different data structures.

I already know exactly what data I need to access through referring to their API docs, but Make does not let me access any of the data elements associated with API events other than the most recent one it happened to experience.

How can I most easily configure my Make scenario to consume the data I want, when the data would come from an API event different to the most recent API event?
