Hi @Marvin Dacuag , It's part of the displayName localization of the claim (Localization string IDs - Azure Active Directory B2C | Microsoft Learn)
XML example:
<LocalizedString ElementType="ClaimType" ElementId="displayName" StringId="DisplayName">Display Name</LocalizedString> <LocalizedString ElementType="ClaimType" ElementId="displayName" StringId="UserHelpText">Your display name.</LocalizedString>
I hope this helps!
Best,
James
