There are two ways to install plugins. You can install them from the cli with npm install nodebb-plugin-soundpack-default and then activate with ./nodebb activate nodebb-plugin-soundpack-default or you can install from the admin plugins page by searching for it and clicking install/activate.

In both cases you will need to rebuild and restart nodebb for the plugin to start working. From the cli you can do:

./nodebb stop
./nodebb build
./nodebb start

In the acp you can simple click restart and rebuild on the dashboard.

I did all of this.
Nothing has changed inside the forum interface.
It's unclear where to look and what to click.
There are no instructions on GitHub
Under the plugins it says that they are compatible with the latest version of the forum. So someone checked. So how do I use them?

This plugin hasn't been updated in 5 years so it is unlikely it will work with nodebb 3.x.

The sound-pack plugin works with the latest version of nodebb and adds new options into the user settings page.

I'm very sorry, but I can't find
Please write the buttons that need to be pressed to get to this page

I found it! You need to click on the user name. Then select settings.
I have very little disk space.
Is it possible to prohibit or reduce the size of files uploaded by users? How to do this?
