Not finding username, client_id or client_secret properly?

I filled out the config aw-watcher-spotify.toml file but when I do `python aw_watcher_spotify/main.py` it says one of those fields isn't specified in the config file. I copied the id and secret right from spotify's dev dashboard. I put a meaningless username in because I'm not sure where to get that from, is there a 'proper' username I should be using?
