No monitoring data found

[crimson_riot]

Hello, I am getting No monitoring data found error while setting up stack monitoring. I learned that the recommended way to monitor a cluster is via metricbeat and I want the elasticsearch cluster to monitor itself which according to the documentation is possible in eck 2.3. Stack Monitoring | Elastic Cloud on Kubernetes [2.3] | Elastic

However I am getting this error.

My yamls are looking like this:
