Remarks
This method calls other methods in this class based on the type of the activity to process, which allows a derived class to provide type-specific logic in a controlled way.
In a derived class, override this method to add logic that applies to all activity types. Add logic to apply before the type-specific logic before the call to the base class OnTurnAsync(ITurnContext, CancellationToken) method. Add logic to apply after the type-specific logic after the call to the base class OnTurnAsync(ITurnContext, CancellationToken) method.
