FMS 26 + Request Let's Encrypt Certificate

Maybe this isn't a new feature but I'm assuming it is. It's great, thanks!

My question is when choosing "Automatically Renew Certificate option" what the process is.

I have to add an email address, so maybe it emails me when the cert renews, as FMS then needs a restart?

Their instructions are not super clear:
