How do you systemd a podman-compose?

Hello,
I encounter the problem that systemd is unable to fully track a starting/running container. The service states stucks at "activating" while container is already fully up and running.
I know there is a way to set up a service file with a tracked PID, but this only possible with the podman run command.
What is the alternative for a composed service file?
There is a open-source project that supports that, but in our offline secured infrastructure is this not possible. see: https://github.com/containers/podman-compose
