Google Calendar notifications sent to attendees despite being disabled in settings

Summary

When adding participants to an existing Group Booking, FluentBooking triggers a Google Calendar notification/invite to the attendee. This occurs even when the "Google Calendar Notification" setting is toggled OFF within the FluentBooking Host settings.

Environment

• Plugin: FluentBooking Pro v2.0.05
• Integration: Google Calendar
• Booking Type: Group Booking

Steps to Reproduce

1. Navigate to Host Settings and ensure Google Calendar notifications are disabled.
2. Open an existing Group Booking appointment that already has at least one attendee.
3. Add a New Person to this slot.
4. Observe that the newly added attendee receives an automated invitation email directly from Google Calendar.

Expected Behavior

The plugin should update the Google Calendar event silently (using the sendUpdates=none flag in the API) when the admin has opted out of notifications in the plugin settings.

Actual Behavior

The plugin appears to be triggering a default update notification via the Google Calendar API, bypassing the internal FluentBooking notification logic.
