I am trying to deploy  permission set using package.xml in sandbox but facing below issue:
1. In field: application - no CustomApplication named standard__AdvancedTherapyManagement found
2. In field: application - no CustomApplication named standard__PublicSectorInspectionManagement found
3. In field: application - no CustomApplication named standard__TrustCard found
4. In field: application - no CustomApplication named standard__Work found
5. In field: field - no CustomField named
Entitlement.SvcApptBookingWindowsId found

These apps and custom field not possible to remove from permission set because code is already in git.

Also I found this help archicle: https://help.salesforce.com/s/articleView?id=000383597&language=en_US&type=1 
It asked to raise case with salesforce

Any other way to resolve without raising case ? and also how to enable Entitlement.SvcApptBookingWindowsId field in sandbox?

I want to know below behaviour is expected in Salesforce regarding Event object.

Please refer below step:
Created Event with multiple Attendees

In background, another Event is get created with Assigned to as 2nd Attendee
Observations:
1. Only original event is editable by only owner of the event
2. Both event is in sync any value change is reflect in another event
3. If we add 3 attendee it creates 3 event in background.

I could not able to find any doc related to this I have tried the same thing in new Org as well I observed same behaviour. Can someone please share some help document related to this behavior and also confirm below behaviour is expected.
