Please help me

Answer 1

It IS possible, but NOT recommended as your referenced documentation said as below.

This example of sending notifications from the client app is provided for learning purposes only. Since this will require the DefaultFullSharedAccessSignature to be present on the client app, it exposes your notification hub to the risk that a user may gain access to send unauthorized notifications to your clients.

If you are making your app for public purpose, bad user could get security key of push notification and could send spam messages. So, to address this issue, you need to create Azure WebApp to register and send push message.
