How can I change environment variable ROOT_URL when using snap package?

Rocket.Chat Version: 0.54.2

DB Replicaset OpLog:
Node Version:

I installed Rocket.Chat by

snap install rocketchat-server

on Ubuntu 16.04 LTS.

How can I change environment variable ROOT_URL so that the server runs in a subdirectory?
I tried editing /etc/environment and /etc/systemd/system/snap.rocketchat-server.rocketchat-server.service as shown below, but they don't work. ROOT_URL with a running server is still http://localhost when I check it by the following command.

sudo od -S1 -An /proc/2730/environ

(2730 is node server's pid.)

/etc/environment

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
ROOT_URL="https://live.oguradio.com/rc/"

/etc/systemd/system/snap.rocketchat-server.rocketchat-server.service

[Service]
EnvironmentFile=/etc/rocketchat_envvars.txt

/etc/rocketchat_envvars.txt

ROOT_URL="https://live.oguradio.com/rc/"

I'm also looking to see how one can change an environment variable, though in my case I would like to specify an external mongo database.

For your usecase, I believe you should be using nginx or something similar, and you can use it to proxy to the rocketchat server.

For anyone that's searching this looks like it's probably related to #4971

Hey, you can change it using this now https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/#how-do-i-change-other-environmental-variables-in-my-snap

While this page (https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/#how-do-i-change-other-environmental-variables-in-my-snap) points out that changing env variables is possible, it doesn't help with the syntax on changing the site_url.
