Notify permission issues

Why applications such as Wechat and Alipay are enabled by default on any mobile phone, while the project I am working on opens by default only on some mobile phones.
I took a look at Alipay. First, uninstall Alipay and then install it. Enter the settings to see that the notification permission is open. And my app doesn"t work. How does it work?
