What does the Discogs plugin?

[make-nz]

Hi all. Am a long time user of JF, but new here.
As with all things you don't know well, you don't know if they work well for you.
I installed the Discogs plugin, put in my DEV-KEY and I can see it as a new meta data provider for my Media Library.

Q:

1. In my existing Lib of tagged flac music CDs I set discogs to provide albumartis meta data,
   but a scan for missing meta data does not bring in any new information/images to my albumartis tab.
   How can I trigger this?
   
   
2. In the plugin setting there ist the option:
   Description markup: HTML | TEXT
   Am I supposed to see any Discogs information on some screens, or a link?
   

Server: 10.9.11 FreeBSDon TrueNas Core 13.3
Plugin: Discogs1.2404.12.0
