Help with OpenSearch Monitors

I have the following Query for my monitor. It is currently triggering the monitor for any 5+ errors over the span of 10 minutes. I need it to trigger for 5+ errors of 3 unique users over the span of 10 minutes. I dont know why its not accounting for the unique users. Please help me!
