eventCategories
Select the event category on which Insights should be enabled.
If EventCategories is not provided, the specified Insights types are enabled on management API calls by default.
If EventCategories is provided, the given event categories will overwrite the existing ones. For example, if a trail already has Insights enabled on management events, and then a PutInsightSelectors request is made with only data events specified in EventCategories, Insights on management events will be disabled.
