I am wanting to follow [instructions to add discourse-maths plugin](https://meta.discourse.org/t/install-plugins-in-discourse/19157)  
only when I edit app.yml I see the existing plugins showing as follows

and then rebuilt the container  
However the maths plugin does not show in options

Should I be editing the yml to take the following format with sudo?

```plaintext
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - sudo -E -u discourse git clone https://github.com/discourse/docker_manager.git

```

I stuck with the old format, corrected a space and rebuilt the container.  
Now I see the Plug in listed in Plugins
