I checked https://api.twitch.tv/helix/users?login=bryan1231
And the “notice” is reporting their display name rather than username/login
I’m unclear what the problem is you are reporting other than the notice using the display name (a few chat events do that see:

You might be interested in

or the related eventsub topics.
But I’m not unclear what the problem is or what you want to get solved?
