Your CalendarHero meeting assistant can add contacts, but cannot edit them for you. These contacts are not added to your Google or Microsoft account, they are only added to your CalendarHero account.
A contact is automatically added if you include their email address in a task like scheduling a meeting or looking up information on them. After you have included their email address, we will try and find additional information for that contact, and you will be able to use their first or last name in future task requests.
