How to use the return of the "get files" action from the SharePoint package?

I'm trying to use Sharepoint functions to obtain a file link so that it can later be used in Excel functions, but how to obtain this data is proving to be a challenge.

Basically I can authenticate to Sharepoint and get results, but specifically the function of getting files is a mystery to me: the return is in a list-type variable and dictionary-type variables are stored inside it (if I understood correctly).

How do I seek a refund in this case? just bringing the list ends up in error, but I have no idea how to bring the data I need.
