Mapping /media in Nginx with Seafile Docker ... where is it?

I’ve installed the Seafile docker per the docker deploy instructions in the Seafile docs (I can’t post links)

I’m trying to set up nginx now … but I’m stumped on what to do with /media… I can’t find the path it wants me to use.

I see a lot of articles about setting this up, but they all say something like this:

...
...

    location /media {
        root /opt/seafile/seafile-server-latest/seahub;
    }

I don’t have any paths like that. The only one I have is /opt/seafile-data

$ tree /opt/seafile-data/
/opt/seafile-data/

│       └── seafile.nginx.conf
└── seafile
    └── logs

My docker-compose file has the data folder setup using defaults:

    volumes:
      - /opt/seafile-data:/shared   # Requested, specifies the path to Seafile data persistent store.

$ locate seafile-server-latest returns nothing

What path am I supposed to put there? I’m not sure what I’m missing.

Thanks in advance!
