How to configure EventBridge to run a powershell document on target machines when ever a CloudWatch alarm is triggered.

Thanks Nabil. Additionally, worth mentioning that all CloudWatch alarms are set in one account and the machines are in a different AWS account. I am certain that I can configure a cross region/account event bridge, but not so sure how I can feed the alarm status into event bus in account A, then pass that on to event bus in account B to then execute the Powershell document. So what would be your opinion of a high level design in this case?
