Cannot install plugin - nothing happens

Hi all, I trying to install the discourse-alt-logo plugin (https://meta.discourse.org/t/alternative-logos-for-dark-light-themes/88502), but I’m failing miserably.
I have already successfully installed several other plugins in my system, this is how my app.yml looks like:

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - sudo -E -u discourse git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/discourse/discourse-voting.git
          - git clone https://github.com/discourse/discourse-solved.git
          - git clone https://github.com/discourse/discourse-canned-replies.git
          - git clone https://github.com/discourse/discourse-alt-logo.git

(Note that the topic about installing plugins Install plugins on a self-hosted site has been recently updated with a "sudo -E -u discourse" prefix before the git clone command. It’s not clear though if the remaining lines should have sudo as well. But I have tried all combinations: everything wit sudo, everything without sudo, just the first with sudo, etc. What is the correct one?).

Here is part of the rebuild log:

However, whatever I do, the plugin doesn’t get installed, no options are displayed, and when I go to the Plugins section in the Admin area, only the previous plugins are listed as installed:

Any ideas?

Alt logo is not a plugin, it is a theme. To install themes follow How do I install a Theme or Theme Component?

Silly me. Thanks for pointing out. By the way, what is the correct way to modify the app.yml for plugins? Should I prefix all git clone commands with “sudo”?
Did you see the “permission denied” in the log above? Could you please enlighten me? Thank you very much in advance.
