Question. How to deploy Elastic Agents in two Kubernetes clusters

Good day

I have a rancher environment with two kubernetes cluster: services and elk

Elastic stack was deployed in elk cluster along with an elastic-agents per node.
The idea is to monitor also the nodes of the other cluster but i don't have any clue about how to do that and also I can't find any information on google.

Do you know if it's possible to link elastic-agents with the fleet server in different clusters or if I need to deploy another fleet server?

Thanks
