Run the scenario
You have a Notion database that you use to track all your upcoming meetings. You want to be able to see these meetings in Google Calendar so you can easily add them to your schedule. With this scenario, any time a new meeting is added to your Notion database, it will automatically be created as a new event in Google Calendar. If any details of the meeting are updated in Notion, those changes will be reflected in the Google Calendar event. And if the meeting is deleted from Notion, the corresponding event will be deleted from Google Calendar.
