The code snippet for tracking custom events does not seem to be right

[bennet-roy]

Issue in ./help/tutorial-migrate-target-websdk/track-events.md

The code snippet under the title "Custom-tracked events" does not seem to be right. In my testing , I do not see an item with schema type "https://ns.adobe.com/personalization/measurement" delivered for a FBC Activity. Not clear what needs to be done on the Activity for such a schema type to be delivered with the propositions. When does such an item get delivered? Can we please add more details on how to implement click tacking with an end to end example?
