I try to add some functions in lambda processEvent.
For example,
tags
actionType
domain
RemoteIpDetails
etc.

found some solutions here
const tags = message.detail.resource.instanceDetails.tags;
const actionType = message.detail.service.action.actionType;
const domain = message.detail.service.action.dnsRequestAction.domain;
const awsApiCallAction = message.detail.service.action.awsApiCallAction.remoteIpDetails.ipAddressV4;
const networkConnectionAction = message.detail.service.action.networkConnectionAction.remoteIpDetails.ipAddressV4;
