The new Customer Service Workspace Case Enhancement Form shows on the right side panel the customer details (customer360 component of the field accountid).

What many Customers in B2B need is also "Contact Details", where we see the customer360 component of the standard microsoft field "primarycontactid".

The reason for that is that while the customer is a company, the main contact refernce is an employee of that company, which is stored in the contact (lookup: primarycontactid).
