wixPaidPlans_onPlanPurchased and auto renewal

I can’t find much information for how a Plan subscription auto renewal is handled and looking for some clarification.

I know that

wixPaidPlans_onPlanPurchased ( event )

(in events.js) is called on the initial Plan purchase. (I have that working in my code.)
Is it also called during an auto renewal?
I’d assume so but wondering how it would work.
If not, can someone explain how I can capture an auto renewal event?

Related question, is there a way to simulate an auto renewal?
