how can get radio values to api with formik?

I want to get radio values and pass them to API with Formik. you can see code below:

<Grid item xs={12} sm={12} md={12}>
  <FormControl>
    <FormLabel>نوع سرویس:</FormLabel>
    <RadioGroup row>
      <FormControlLabel
        value={ServiceTypeEnum.Went}
        name="ServiceType"
        control={<Radio />}
        label="رفت"
      />
      <FormControlLabel
        value={ServiceTypeEnum.Return}
        control={<Radio />}
        label="برگشت"
        name="ServiceType"
      />
      <FormControlLabel
        value={ServiceTypeEnum.WentReturn}
        control={<Radio />}
        name="ServiceType"
        label="رفت و برگشت"
      />
    </RadioGroup>
  </FormControl>
</Grid>

do you prefer to use enum for this solution?

im reading radio component n mui and find below code:

 <FormLabel>نوع سرویس:</FormLabel>
                                    <RadioGroup row
                                        onChange={handleChange}

                                        defaultValue={ServiceTypeEnum.Return}
                                        name="ServiceType"
                                    >
                                        <FormControlLabel
                                            control={<Radio />}
                                            label="رفت"
                                            value={ServiceTypeEnum.Went}
                                        />
                                        <FormControlLabel
                                            control={<Radio />}
                                            label="برگشت"
                                            value={ServiceTypeEnum.Return}
                                        />
                                        <FormControlLabel
                                            control={<Radio />}
                                            label="رفت و برگشت"
                                            value={ServiceTypeEnum.WentReturn}
                                        />
                                    </RadioGroup>
