Observability : Install standalone Elastic Agent - No agent information in Kibana

HI ,

I have installed docker ealsticsearch . I installed agent on the docker host machine ( in Install standalone Elastic Agent on your host option ) . The installation finished and prompted "Go back to Kibana and check for incoming data" ,

The Kibana "Visualize your data" is looping forever . I checked logs->Explorer . There is nothing ( no agent machine ) . Can anyone share your experience how to install agent in Docker machine ? Thanks
