The combination of `StringEnumConverter` and `EnumMember` does not work

    [JsonConverter(typeof(StringEnumConverter))]
    public enum Language
    {
        [EnumMember(Value = "en")]
        English,
        [EnumMember(Value = "de")]
        German,
        [EnumMember(Value = "ende")]
        EnglishAndGerman
    }

    [JsonConverter(typeof(StringEnumConverter))]
    public enum Language
    {
        [EnumMember(Value = "en")]
        English,
        [EnumMember(Value = "de")]
        German,
        [EnumMember(Value = "ende")]
        EnglishAndGerman
    }

    public partial class ContentCreation
    {
        [JsonProperty("name")]

    }
