notifyEvent abstract method
Called by Digia when a rendered experience emits a lifecycle event.
Plugin must translate and forward to the CEP's analytics API: CleverTap: syncTemplate (viewed/clicked) / dismissTemplate MoEngage: trackSelfHandledImpression / etc.
payload.cepContext carries CEP-specific identifiers the plugin wrote during _mapToInAppPayload() — use them here for correlation.
Implementation
void notifyEvent(DigiaExperienceEvent event, InAppPayload payload);
