Enable notification sound when phone screen is off?

[SolarDesalination]

So happy there is a PWA Pomodoro app that's not overly complicated.

Is there a way or would it be possible to add the ability to have the notification sound play if the phone turns off the screen? Currently I can't use it as a timer on my phone because when my screen shuts off I don't get the notification.

Upon further reading it might be that this is a push notification feature that's needed..

Push notifications are already implemented. Unfortunately, iOS does not support them in PWAs and on Android I couldn't manage to make them work reliably with the screen off.
