Scoping Microservices

Dears,

we build two microservices the first is a notification microservice that is responsible for sending and handling notifications like SMS, Email, and App notification ...etc and the second is a service catalog to define the information and configuration of services like service name, description, activation status active or not and ...etc.

My question is if I have configuration about service like allowed notification types that can be used by the service for example service A can send only SMS, and Serivice B Can send Email & SMS.

what is the proper service to define this configuration?

set this configuration as metadata in the service catalog or set in the notification as configuration
