When I add set the IP of a domain to point to caddy, do I have do tell it some how to Caddy, or the certificate is created on the fly on the first https call?

It's really important for us https://news.ycombinator.com/item?id=43053955 due to our need to redirec apex domain to www ... which we can solve with the free (great) service provided by https://www.apextowww.com/#get-started ... but, we are just curious since https://www.apextowww.com/#get-started does use Caddy (I see it in their headers) so maybe we would just need Caddy :)
