How to use ffmpeg on Railway by writing in nixpacks.toml?

I developed a Discord Bot on Heroku and am considering migrating from Heroku to Railway. I used the following buildpacks on Heroku. https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git https://github.com/Crazycatz00/heroku-buildpack-libopus.git I would like to know how to write in nixpacks.toml in Railway. I am not looking to create a music bot, I am looking to create a bot that reads text on discord. I understand that knowing how to do this may encourage the creation of music bots, so could you please DM me about how to do this? Incidentally, the following description does not seem to work.

[phases.setup].
  nixPkgs = ['python39','ffmpeg','libopus'].

[phases.setup].
  nixPkgs = ['python39','ffmpeg','libopus'].

I get an error like this

Ignoring exception in on_message

If you host music bots on the platform you’re probably gonna get banned Just a heads up ^^Know that you said you weren’t I’m putting this disclaimer there for people who find this thread

As I stated in the text of my question, I fully understand that hosting MUSIC BOTS is prohibited. I will never host a music bot, and if I do, you can ban me. This is a technical question for running a build with nixpacks.toml on Railway and I believe it is a useful question for users to use Railway's services. And I understand that this method should not be made public, so please let me know how to do this via direct message. What is your final conclusion? In this case, does it mean that we cannot build & deploy in the way we describe in nixpacks.toml? Why am I getting an error when I have libopus in nixpacks.toml?

Yes it does. But I get a raise OpusNotLoaded() error as I wrote above. Is there something wrong with the way libopus was introduced?
