How to connect to remote system?

[CodeOxymoron]

How do I get a remote SSH connection working?
All the documentation on the Container Desktop website talks about running Container Desktop and Podman/Docker on the same computer. I don't see documentation for remote Podman/Docker installations.

I have installed Container Desktop 5.2.13 on Ubuntu 24.04 using flatpak and it launches.
I would like to connect and manage a Fedora IoT 42 server running Podman 5.5.0.

These are the settings I have so far:
Container Engine = Podman
Container host = Remote SSH connection
Path to ssh executable = /usr/bin/ssh
SSH Host = the server I added to the ssh config (I setup and tested the ssh key pair)

When I try to connect, the log window stops at "SSH connection has been established" for about 30 seconds.
Then the window returns to the main screen and I get a notification at the top that says "Connection skipped - please check the settings or install the requirements".
What settings do I need to change?
What requirements need to be installed? The documentation for Container Desktop does not mention anything that I have found yet.
