Notifications do not send to IOS and Android Apps

I followed the white-label documentation and customize the React native App.
Now Notifications did not send to my customize app but when I download the Rocket.chat app and put my server URL then it shows notifications. but did not show in my app.
In android and Ios, both apps do not show.
