~ $ claude --allowed-tools "nango" \
Build a custom Nango SYNC for Google Calendar called “calendar-events”.

The sync should fetch all events from the primary calendar of the connected user.    

It should run every 10min and output the events in the following schema:
[....]

Use `nango dryrun calendar-events test-user-1` to test.                                
~ $ npm i -g nango
~ $ nango create --sync google-calendar calendar-events
Sync scaffold "calendar-events" created for "Google Calendar" integration           

~ $ nango dev # watch & auto compile
~ $ open google-calendar/syncs/calendar-events.ts

~ $ nango dryrun calendar-events test-234 # test locally

~ $ git commit -a -m "Google Calendar events sync"
~ (main)$ nango deploy dev
