DeviceEventEmitter is deprecated, but we can use NativeEventEmitter instead

Yeah, currently we don't use NativeEventEmitter anywhere in the codebase, so I think now it's better to keep DeviceEventEmitter and later (when needed) we can re-work all code pieces at once.

Would it fire when we open the first chat? It looks like it would, so we can skip it or change the log '[E2E] Message verification failed,' as it may look like an error, but it would be expected behavior since we only want to check it for entry.name === SWITCH_REPORT

if (!!res && res[0]?.item?.reportActionID === linkedReportActionID) {
appearMessageResolve();
