If your Google Calendar interrupts you by switching away from whatever you were doing and going to the Google Calendar tab, we have the solution.
(Please note: This used to be a Labs feature that graduated to become a full supported feature)
- Go to Google Chrome and click on 3 spots in top right corner.
- Click Settings and scroll to bottom of page
- Click Advanced to reveal more settings
- In the Privacy and security section, click on Content settings…
- Click on Notifications section and be sure Ask before sending is turned on
- Click Add button to add a site to Allow list.
- Add “calendar.google.com:443” in the field and Add in the drop-down
- Now, your notifications should look like this when you go to Calendar settings. (If not, tick both boxes)
Now your Google Calendar will only show a pop-up reminder.
