Undocumented features in /v3/applications/settings_global

[Problem/Question]
Get global application settings | Chat Platform API | Sendbird Docs documents a good deal of the settings returned from the /v3/applications/settings_global endpoint, but there are some settings I can’t find any information about. Are these all deprecated? Does anyone know what they do?

    "file_filter": {
        "type": 0,
        "regex": ""
    },
    "invitation_acl": {
        "muted": false,
        "operator": true,
        "member": true
    },
    "text_moderation": {
        "doNotStore": true,
        "languages": [],
        "requestedAttributes": {
            "TOXICITY": [
                {
                    "scoreThreshold": 0.9
                }
            ]
        },
        "moderationLevel": 0
    },
    "user_messages_per_channel": -1,
    "user_messages_per_channel_duration": 1
}

I can’t answer everything for your question but there’re more information in Sendbird Docs.
