c# - How to force JSON enum to save as TEXT instead of a NUMBER

This enum property:

public enum MinimizeActionEnum {
  NONE = 0,
  CLEAR = 1
}
    
public MinimizeActionEnum MinimizeAction { get; set; } = MinimizeActionEnum.NONE;

It is saved as INT by default:

"ReportParams": [
{
  "Name": "pProdId",
  "Description": "",
  "MinimizeAction": 0
},

With using that attribute:

[JsonConverter(typeof(JsonStringEnumConverter))]
public MinimizeActionEnum MinimizeAction { get; set; } = MinimizeActionEnum.NONE;

the enum value will be stored as TEXT:

"ReportParams": [
{
  "Name": "pProdId",
  "Description": "",
  "MinimizeAction": NONE
},
