IIOT OPCUA Alarms and Events node-red - node.js

Question

I am working on OPC DA & AE. For that, I am using the IIOT OPCUA node in Node-red.
With the IIOT OPCUA node in Node-red I am able to connect and access data but for accessing the alarms and events not getting what to do.
I have tested my OPCAE server with the OPC expert tool and it's working fine but I want to execute alarms and events with Node-red.
Please help me out regarding this issue.
Thank you.

I haven´t worked with alarms and events yet but you or other people interessted may have a look on this discusion.
OPCUA-TEST-NODES.json contains an examples for testing events:
