Can we use other services instead of pusher?

I have a small forum on freeflarum, it has 50 users and 20 users online mostly.I use pusher to make the posts can see real-time without refresh like Pusher extension, and cooperate the PWA extension to achieve the notification in PWA App.
Because of I and all users are in China, the Pusher websocket server can't use in China.
But I see that Cloudflare have "Workers", and we can visit it in China properly, so can we use it instead of pusher?
Or use some other services that friendly to China's special network environment?
Or some extensions that having minimal overhead for freeflarum's servers to achieve similar or identical effects?

Nodeloc

You can change the url of pusher.js to let it work in China.

I found that pusher works properly now.
I'm foolish.
But why I can't receive notification in PWA??
(I will ask it in PWA extension posts.)
