Authenticating a postman client on local .net core API

I am having some problems while authenticating my postman against my local .net core api
The authentication via browser works like a charm

I followed successfully this guide until the “Access Token to Call Protected Endpoints” section, but then i can’t get my local api to know that i am authenticated as a postman client

After i call an endpoint marked with my [Authorize] attribute i get correctly redirected to auth0 for authentication, i am already authenticated there so i get the following html page in response

Obviously postman does not execute the javascript code by itself so those parameters never reach my local .net core api

What am i doing wrong?
If needed i can provide additional details about my configuration but i think in this case it’s more of a conceptual problem, like if i misunderstood something

Sorry for my bad english, i am not english native
