Domain.cfg.lua missing in etc/prosody/conf-avail

Hi,

I am trying to enable authentication when creating a room and I used the quick install method. However, the file for me to edit authentication is missing, ( fqdn.cfg.lua) in etc/prosody/conf.avail).

Here is the link that I saw (https://jitsi.github.io/handbook/docs/devops-guide/secure-domain).
