Explain Debug mode for this plugin

[vmiyoshi]

As you can see from the output below, I have added debug mode per-instructions. However logs show the entry isn't used and can be removed.
[11/29/2023, 5:53:40 PM] [Deebot] Config entry [debug] is unused and can be removed.

{
    "name": "Deebot",
    "countryCode": "US",
    "username": "username",
    "password": "password",
    "debug": "true",
    "devices": [
        {
            "label": "name",
            "deviceId": "id"
        }
    ],
    "_bridge": {
        "username": "00:00:00:00:00:00",
        "port": XXXXX
    },
    "platform": "Deebot"
}
