Vault Agent on Windows - specify log file?

If running the Vault Agent on Windows as a service, how do I redirect the log to a file?
I found this issue here - It said this was addressed in a PR in consul-template in November.

I’ve downloaded the latest Vault agent binary for Windows, and it ignores a “-log-file” cmdline option, and it ignores a stanza like this in my vault-agent.hcl

log_file {
  path = "./vault-agent.log"

Ugh - for some reason I thought this was addressed in Vault, but it appears to be in an entirely different product?

I’ve still got the question - how do I get Vault agent logs somewhere if I run it as a service on Windows.
