How to add new internal type activities to the resource to block available capacity?

Summary:

showBookingGrid API returns timeSlots as available regardless there is an Internal activity assigned to the timeSlot, when the internal activity has been created with timeSlot field informed.

We detected this behavior when adding an internal activity to the resource:

1. We add to the only available resource an “Internal” type activity 4 hours duration from 12AM, in this case the activity type is “Lunch”. This activity type has timeSlots of 12-15 and 13-16 configured.

2. If we add the internal activity without informing the timeSlot field, the query to the showBookingGrid API returns the timeSlots from 12:00 to 16:00 as NOT available.
