How to configure other beats through elastic-agent standalone in kubernetes Cluster?

Hello Everyone , In my project we have to install elastic-agent standalone in our kubernetes cluster as Daemonset. I did that and i can see kubernetes metric and pod logs from Dashboad and Discover.
And , If i go inside the elastic-agent pod and run the ps -ef command then we can see metricbeat and filebeat process are running but i need to installed all the other component and beats like heartbeant or APM as well through elastic-agent.
Request you to please help me out how we can configure or enable other beats ?
