How to sync Google Calendar and Evolution mail?

I am trying to sync Google Calendar with Evolution email client. But I am not able to do so. I tried some of the steps given in web to include Google Calendar and infact I am able to see my entries that I created in Google Calendar

Problem is I cannot save any new appointments entries to Google Calendar through Evolution. Please help me.

This will help you.

With Two-Factor-Authorization (2FA) enabled on your account and/or Google for Business:

1. Create a new app password for your Google Account (save this somewhere)

2. Create a new Calendar in Evolution (File -> New -> Calendar)

   URL: https://www.google.com/calendar/dav/<your email address>/events/
   User: Your full google account ([email protected])
   Check "Server handles meeting invitations"

   Click "OK" and enter your app password, not your Google password.
