Let's Encrypt SSL cert for virtual host with Webmin

I know how to get all my virtual hosts served securely with Virtualmin.

But for the first time, I decided to use a small machine (one managed by WEBMIN only) to also host another web site. I did that by adding a new virtual host via the: Webmin > Servers > Apache Server options.

So now I am not sure if I am able to use Webmin in any way to get the Let's Encrypt SSL cert for this second virtual host. I looked in the obvious places but there doesn't seem to be such an option anywhere I looked. Is this something not available on Webmin? Or am I just missing something like a module?

I'm not talking about the SSL certificate for the Webmin server itself -- that works flawlessly.
