Oracle Fusion financials REST batch action how to reference ID from a previous part

Summary:

How to reference between parts in a a batch action.

Content (please ensure you mask any confidential information):

I have a situation where I currently make 8 separate rest calls into fusion ERP to create different objects. They are dependent on each other in the sense that call number 2 needs the ID returned by the call number 1 etc.

I reviewed the Perform Batch Actions in the documentation here

But from that documentation and the examples I cannot figure out how to populate the "path" for the second call.

As an example I tried from postman to create a payload with two parts: Create a supplier and then query (get) that supplier afterwards. See the example payload.
