Usage
This function runs automatically, so it is not called manually. Is this incorrect?
Additional Notes
This function should be supplemented by adding a project-specific set of event tracking in a child theme JavaScript file.
If the Event Intent custom dimension (in Nebula Options) is used, each click event is associated with an “explicit” or “intent” dimension (for right-clicking or middle-clicking).
For a list of all events tracked by Nebula, see [page coming soon].
