How to send f.e. install app to specified user channel?

I read Mobile User Logins and Users in macOS documentation and whole thing, but I still don't know, which key should I attach to send configuration like install app to specified user on Shared iPad. When user logs in first time I received:

- Pushmagic always the same
- Token - always different 
- UDID - always the same
- UserID - FFFFFF-FF....
- UserShortName means AppleID

What should I do to f.e. this plist to send app to user container?

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" ""><plist version="1.0">
