Can you generate swagger.json with enum with default values?

Question

I have a controller method such this

public ActionResult<MyEnum> ReturnEnum()
    {
        return MyEnum.one;
    }

where

public enum MyEnum
    {
        one = 1,
        three = 3
    }

what I need is to make OpenApi generate such json, where there are default values of MyEnum . Instead I get this

 "MyEnum": {
        "enum": [
          "one",
          "three"
        ],
        "type": "string"
      },

To be honest I am not sure if it is even possible or how should it look like (something like ->

"enum": [
          "one" : 1,
          "three" : 3
        ],
        "type": "tuple"

) but I didn't find anything in docu. Don't be too harsh on me if it's stupid one, I'm just starting with this stuff.
