List of components - Badge for quiz completion

HI All,
For badging,
“For new badge types that you create, specify an Issuing Component value that identifies the software component responsible for issuing the badge. For example, if badges are issued by the course management component, you might define Issuing Component as platform_course; if badges are issued based on activity in course discussions, you might define Issuing Component as platform_discussions.”

To issue new badges based on number of quiz completed, eg. Completed 10 quiz.
I need to find the Issuing component. Should it be
platform__problems? platform__quiz?

Thanks
