Running an existing app as service

[Android Central Question]

I'm using yandex browser and getting notifications when app is in foreground.

I would like to receive notification s when screen is off / app is in background.

Any ideas ??

Are we talking about the notifications that websites can push to the browser?
If so, handling these notifications while in the background may be a feature that not all browsers have.
Have you tried other browsers?

(I am not going to be much more help here as I have turned off this feature in all the browsers I use.)
