Interface_config.js changes don't apply

The changes that I make at interface_config.js does not apply.

I am on a Debian 10 and installed the jitsi meet package by following the quick install instructions at https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md.

domain-config.js changes work fine.
domain-interface_config.js changes does not work.

Before customizing, I copied the file interface_config.js located at /usr/share/jitsi-meet to /etc/jitsi/meet/domain-interface_config.js and in /etc/nginx/sites-enabled/domain.conf I included an alias

location = /interface_config.js {
alias /etc/jitsi/meet/jitsi.freemath.xyz-interface_config.js;
}

What am I missing? Could someone please help?

(I noticed several posts pointing out to the same issue but none of them has the solution as far as I could see.)
