Current behavior

when we minimize the browser or inactive tab of application, then notify event does not trigger. https://stackblitz.com/edit/ngx-countdown-setup-nglzm2?file=src%2Fmain.ts,src%2Findex.html

Expected behavior

It should trigger notify event at a time even if we change the tab or minimize the browser.

Environment

Angular version: 14.1.0

ngx-countdown version: 12.0.1

This happens for For Background Tasks (non-UI related), and it looks like it can only be solved using HTML5 Web Workers. Here are some related articles:
