Need a method for managing systemd services across multiple hosts

I have six Linux servers running RHEL 8.6 - and need to ensure that one specific service is running at least one and at most one of those six servers. Does systemd support something like this? If not, is there an extension to systemd or another mechanism that provides the exactly-one-instance is running across a pool of servers? The question here - https://unix.stackexchange.com/questions/224022/systemd-support-for-toggling-mutually-exclusive-services - starts to get at the question, but it still seems limited to services running on a single host.
