Display name and Email address are the fields Mateo can recommend she modify.

The Display name is a personal profile field that users can edit in their Google Account or profile settings so she can change how her name appears to others. The Email address is part of her contact information and can be updated where account settings allow users to manage their contact addresses.

Department is usually an organizational directory attribute that is managed by an administrator and not something an unmanaged user can reliably change.

Avatar image is not the focus of this question and may be handled through account picture settings rather than the directory fields referenced here, so it is not one of the recommended profile fields in this scenario.

Job title is another directory attribute that is commonly set by administrators and is not typically edited by an unmanaged account holder.
