Probably I am missing something, but I am unable to install the lazy-yt plugin in my new deployment of Discourse (v2.7.7). I searched the docs and this messageboard for answers without results.
According to this topic Install plugins on a self-hosted site the plugin should be added to app.yaml file (I am using the discourse_docker image for deployment). But it seems that the lazy-yt plugin is included with a default installation of discourse, see https://github.com/discourse/discourse/tree/main/plugins/lazy-yt. Also the code for this plugin is not hosted in a standalone repo, so not sure how to refer to this plugin from app.yaml file.
In my new Discourse deployment I am not seeing any settings related to the lazy-yt plugin:
@IAmGav thanks for the welcome! In hindsight it is obvious these plugins are installed by default considering they are part of the core codebase.
I am upgrading an older installation, which previously did require a separate install of the lazy-yt install. So that explains my stubbornness in this matter :).
