I am trying to add useful event logging to my webapp. I know it is recommended to use default google analytics events, but my case does not really fit well in the default events.
In the documentation below: why do i need to configure a map with "Index" properties? I would think that i can just use the name configured in the custom dimension in the event parameters? What does this index even refer to?
