Hi,
I'm not sure that I understand right your request.
The threads you linked where for HikaShop but HikaMarket have his own notification system.
You want to be notified for every orders but HikaShop already send notifications to the administrator for the orders.
You can also use the notification of HikaMarket for the main vendor and add "users" to your main vendor with the "order / notification" acl right.
And using the option to filter the status for the order notification, you can choose for which order status notification you want to notify your vendors.
