Move hardcoded values to environment

[hrideshmg]

The role, channel ID's and root REQUEST_URL are currently hardcoded, they might be liable to change in the future so it would be ideal to have them imported from the environment.

Also since the number of groups could change in the future, their handling needs to be more dynamic.

Is this done?

I don't think so, feel free to take it up

Nevermind, it is addressed in #51. Also, closing this issue as it's a subset of #30.
