Twitch and Xbox account

I mean it wouldn’t be unlimited number of fields returned, at most it’d be 1 attribute whose value is an object with at most 4 platforms(Steam, Xbox, Playstation, Stadia). My use case is for my project, I wanted an easier way to be able to not rely on the player’s PUBG gamertag to look up their Twitch because not everyone uses the same name on both platforms. Maybe I would be able to filter users where their connection includes or is xbox and if their gamertag is what im looking for.

I don’t know how to quote on this thing but that’s exactly what I’m saying, if Twitch gives users the ability to make their xbox connection gamertag public then I don’t know how that’s a privacy issue? Please explain. and thank you for the link.
