hCaptcha: Event Logging for hCaptcha-related events coming from the MobileFrontend editor
Closed, ResolvedPublic
Actions

Description

Summary

Currently, the MobileFrontend integration issues track calls for hCaptcha-related events (since it calls javascript code from ConfirmEdit, which does those calls automatically).
However, there's no code in WikimediaEvents to turn those into interaction events sent to the analytics data lake.

Acceptance Criteria

hCaptcha-related events originating from the MobileFrontend are recorded in the event log

Testing notes

I have not paid much attention to which events are being fired in which editors and under which circumstances. Therefore, a developer could take this up.
