should we have a TODO to change the enum name to
APP_BANNER_EVENT_SUCCESS_ACTION_TRIGGERED or something potentially less verbose.

It would be good to make that a bit clearer (for this and native app banners)

Done.

comment doesn't seem applicable (or needs further explanation that "added to
homescreen" is actually a proxy for X)

Yeah, I probably copied it
