Postman integration - how to or videos

Hi

Is there any videos explaining the integration with Postman API libraries, a step by step guide to load the different endpoints into studio?

As I understand, Uipath connects to Postman and uses the “connection” from Postman instead going directly from Uipath to the endpoint, but I’m missing some pieces to connect Ui with Postman.

I have made a working POST request in postman and retrieves a list of orders in an XML format, but how do I import it to Studio to work with it as a xml file to be looped through?

Maybe I just don’t see the point, but what is the benefit of using the Postman collections as libraries or just creating the endpoints as librariy activities?
