integration – Sync Google Calendar to Toggl?

I’d like to sync the time of my Google calendar events to Toggl using integrations (e.g.: using webhooks).

If some events are overlapping events, it should also not add twice the time entries, to not count time twice. I’d like this to start from now, without including past events of the calendar.

I’m sure there are ways to do this by tinkering with integrations and web hooks.
Thank you for the help!
