Hermes

Hermes allows you to create a pipeline for sending push notifications to your app's users depending on the parameters you push to hermes.

eg - Send this msg to all the users who are using dark mode and have app version 2.1.1

Data can be queried using a combination of GraphQL and Custom metadata query.
