Sending bulk push notifications in ios?

Question

iOS

Hello.
The task is to send 5-20 million push notifications every day to Apple devices, preferably to everyone at the same time (with a minimum difference).
I want to do the implementation on the node with the node-apn package.
The problem is that you can only send to 1 device. Thus, for 1 request, approximately 200ms will take a very long time for everyone.
How to raise thousands of node processes or how to implement such a dispatch?
