Hello Alex, thanks for your time.

I understand the application/service principal whose client id is mentioned is actually used to sign-in the user, example, "noor@domain.com", who has got appropriate authorization on a set of objects in a schema of Unity Catalog.

I do not see in the sample code in the below link a way to specify this user name ("noor@domain.com"). Can you please guide -
