How to send badge count for each individual client ?

When notification arrives for an app in background, the badge is displayed and the count is what is sent from server.
Push.send({
badge: 5, //**This puts badge count 5 for all users**.
query: { // this will send to all users },
});

How do you set badge count for all individual clients ?
How about if
Push.setBadge(9);
from client api should set the badge count for that client in the raix:push database and when Push.Configure({ **badge:true**}) then
Push.send({
badge: 1, //**This should increment by 1** the badge count of the receiver as stored in the database.
query: { // this will send to all users },
});

Any idea how to set badge count individually for each client?
As such Push.setBadge(9); does nothing when app is in background.

Start by tracing the Push.send, Push.setBadge, and Push.Configure APIs and how badge values are represented in the raix:push database. Compare client-side badge updates with background notification delivery. Done means each client can retain an individual badge count and a sent badge increment updates recipients independently.
