To set up the new record types for Person Accounts, the administrator should configure Individual Record Type Mapper custom metadata. The Individual Record Type Mapper is a custom metadata type in Financial Services Cloud that defines how records are created when using certain features, such as Einstein Data Capture or Salesforce Inbox. The Individual Record Type Mapper maps Person Account record types to Individual record types, so that when a new Individual record is created from an email or calendar event, it automatically creates a corresponding Person Account record with the same record type. To configure Individual Record Type Mapper custom metadata, you need to go to Setup > Custom Metadata Types > Individual Record Type Mapper > Manage Records and create a new record for each Person Account record type and its matching Individual record type.
