How to Auto import events from my website to google calendar

Hi,
I have events in my website, I tried to import the events by option “Add to Google” from plugin calendar but its NOT showing any event in my google calendar. Here is my sample calendar link,
URL : https://supraint.ipower.com/works/kiran_test/?page_id=2

Also when i tried the URL option from google calendar and download the ics file then ‘Import calendar’ option it shows me all the events from my site.

I want to know will this work automatically once added to google?

Please help me in this issue.
Thanks,
Etest
