I've set up a GitHub workflow using the myoung34/github-runner template in Railway, and it's working well. However, I want to optimize it by using an internal database URL instead of a public one to avoid egress traffic, but the runner doesn't seem to recognize the internal URL.

Is it possible to configure the runner to connect to an internal database URL within Railway? If so, what would be the best approach to achieve this?

Thanks in advance for your help!
