Issue Summary

• Cal.com - Teams paid plan user.
• Workflows are enabled upon When new event is booked and Disable default confirmation emails for attendees is enabled.

I need to confirm the new events booked using /confirm API call, when I call the API, pending events are confirmed, but the workflow that is supposed to be triggered upon When new event is booked does not get triggered. Manual "Confirm" on the bookings page does trigger the workflow.

Steps to Reproduce

1. Create new event
2. Enable Request confirmation
3. Create webhook subscriber that will confirm the booking using its booking UID.
4. Enable When new event is booked workflow and enable Disable default confirmation emails for attendees
5. Book an event.
6. Event is confirmed via /confirm API

Actual Results

Actual result: no notification email is sent as set in the Workflow.

Expected Results

Expected: API confirmation of a booking should have triggered the workflow.
