Normalizer lowercase not found

Hi @M.Ronge

In settings, how do you configure the "normalizer"?
It would be something like this:

"settings": {
    "analysis": {
        "normalizer": {
            "lowercase": {
                "type": "custom",
                "filter": ["lowercase"]
            }
        }
    }
}
