How to display additional fields of the address book in an anrodid phone?

Question

Android

Hello
, look, let's say in the Google address book I fill in custom fields for the phone number: the subscriber's address, and his debt to pay for services (this will need to be synchronized with the CRM Google address book).
I would like to display these fields on the mobile screen when this number calls.
Maybe someone knows a ready-made solution? And if not, is it theoretically possible to implement this? (As far as I understand, Android cannot do this out of the box.)
