3. Authorize and Select Calendars

   Follow the on-screen prompts to authorize Notion Calendar access to your Google account and select the calendars you want to sync.

Sync Notion Database Entries:

1. Connect Notion Workspace

   In Notion Calendar, navigate to "Settings" and then "Notion." Click "Connect" next to "Add Notion workspace."

2. Grant Access

   Authorize Notion Calendar to access your Notion workspace.

3. Add Notion Database

   Scroll down in the left sidebar of Notion Calendar and find the connected workspace. Click the three dots next to the desired calendar and select "Add Notion database."
