Promethus integration with Kie server issue

I am using Drools Workbench Docker image and Kie server Docker image. i need to expose the Kie server rest point for Prometheus metrics. For this i updated the standalone.xml , standalone-full.xml and add this org.kie.prometheus.server.ext.disabled system property to false to enable the Prometheus extension and restarted the Kie server. but kie server is not exposing the rest resource. RESTEASY003210: Could not find resource for full path: http://localhost:8280/kie-server/services/rest/metrics error occurred when i try to hit this endpoint http://HOST:PORT/SERVER/services/rest/metric although i updated the standalone.xml as it is mention in documentation.

i dont know the reason. very less information is available online, Kindly update this issue.
