Before you can schedule a Webex meeting or Webex Personal Room meeting, you must specify the Webex site to use with your account.
In Google Calendar, select Create event.
Under Event Details, select Add conferencing, and then select Webex meeting or Webex Personal Room meeting.
If you don't see these options under Add conferencing, your administrator hasn’t installed the Cisco Webex for Google Calendar app. You may be able to install the app yourself. For more information, see Add the Cisco Webex App from G Suite Marketplace.
Under Add location, you'll see either Authorize or Login required:
To authorize, choose the G Suite account that you want to use with Cisco Webex for Google Calendar.
Enter the Webex site that you want to use to schedule meetings and select Next.
Conferencing details are added to the meeting.
If you want to continue to schedule a meeting, see Schedule a Meeting, otherwise select Cancel event creation.
