Mapster.JsonNet does not support Enum to string mapping

The following code attempts to map a JObject to a string.
However, the result yields the enum's int value instead of its name.

       //...
        typeAdapter.EnableJsonMapping();
        dynamic model = new JObject();
        model.enumValue = DomainEnum.Three;      
        var result = mapper.Map<string>(model);  // {  "enumValue": 2 }

• Setting up typeAdapter.Default.EnumMappingStrategy(EnumMappingStrategy.ByName) did not change the result
• Setting up the default serializer settings to use StringEnumConverter did not change the result
• Using the attribute [JsonConverter(typeof(StringEnumConverter))] on the enum did not change the result
