I would just trim off the rotted part till you see good uninfected part. Apply lightly some cinnamon as fungicide on the exposed cut part. It will eventually heal and will grow new leaves below the cut off point.
Just remember Dracaena marginata, prefers to be on the dry side. So practice better watering intervals in the future. It is also normal for the plant to shed off lower older, leaves, so never be tempted to overwater. No fertilizers, just let the plant recover on its own pace. Good luck!
