Web Notifications custom implementation vs third-party services

Question

I need to implement web notifications for some website and send notifications from php script executed in console.

I found that is possible to implement web notifications without using third-party services, by using this lib https://github.com/web-push-libs/web-push-php Here is good tutorial https://web-push-book.gauntface.com/

But there also are some third-party services that provides sending web notifications, like:

https://onesignal.com/webpush https://pushalert.co/ https://pushpad.xyz/

and others.

1 - What benefits from using this third party services ?

2 - Is there some limitations when this feature is implemented without using these third-party services ?

3 - How third-party services send notifications, are they using they own push service ?
