Need to enable the option to run "Client Notification" options for devices under Deployment Monitoring Status Node
Under Deployment Monitoring Status Node especially while checking a deployment status we get to see error category node and double clicking the same would provide us the list of machines under that category. We need to enable the client notifications under this just like we run client notification actions on collections or devices inside a collection.

I exactly noted this is missed in 1810, it is already done for devices node but not for devices list upon double click of a deployment status
