Symfony APi平台在api doc中呈现枚举类型

Question

I am using Api platform to create base endpoints and documentation. For this purpose, I use DTO . One of my entity, which converts to DTO, has an enum type which is based on Myclabs/Enum - in doctrine, it mapped like (smallint).

I want, API platform renders this enum, not like the simple scalar value but like nested object with key-value and label - title

For example:

class Choice
{
   /**@var string **/
    $name;
   /**@var int (can be only 1 or only 2) **/
    $measureUnitType;
}

measureUnitType:

class MeasurementUnit extends MyCLabs\Enum\Enum
{
    private const METRIC = 1;
    private const IMPERIAL = 2;
}

So I want the next output:

{
   "name": "testName",
   "require": {
     "value": 1,
     "label": "IMPERIAL"
   }
 }

I have read this piece of doc but honestly, I didn`t realize how achieve my goal
