Nintendo Switch Games: Third-party services sharing definitions

My young child has a game which has established a sharing relationship with his “supervised” account. I got an email from Nintendo confirming this and went into the account to see what it says. From the “Settings for individual third party services” section, it says:

Information received: Basic profile

I cannot find a definition of “Basic profile” anywhere. I can make some assumptions about that, but I’d prefer to know the exact legal definition that Nintendo uses.

Does anyone know where this stuff is defined? Searching the internet for the string “basic information” along with “nintendo” and “sharing” isn’t exactly very targeted. 🙁
