Under personal settings there is a SSH Keys tab that allows you to add new keys. The description says "SSH keys allow you to securely connect to your Railway services via SSH." I've been using the CLI instructions documented here: https://docs.railway.com/cli/ssh, without adding any keys.

As far as I knew there was not a out of the box way to SSH in with true SSH. Is there actually a way to do it with the SSH Keys option? What are the options for? I wasn't able to find docs for it.
