antd Select Option not rendering when entering text in React Hooks

I'm trying to implement a search box with remote data using antd's Select and Option. I'm expecting that when I enter text into the search box, a list of options will be rendered immediately. Instead, the options only appear after when I clear the search box.

I have these states:

const [symbol, setSymbol] = useState("");
const [searchResults, setSearchResults] = useState<React.ReactNode[]>();

and this component:

<Select
  showSearch
  value={symbol}
  onSearch={handleSearch}
  onChange={handleChange}
>
  {searchResults}
</Select>

This is my handleSearch function:

const handleSearch = (value: string) => {
  if (value) {
    fetchStocksList(value, (data) => setSearchResults(data));
  }
};

This is the function used to fetch data from an api, the console.log() below can correctly log the data that I wanted:

const fetchStocksList = (
  value: string,
  callback: (data: React.ReactNode[]) => void
) => {
  axios
    .get(`${API_SERVER}/api/stocksinfo?search=${value}`)
    .then((res) => {
      let data: React.ReactNode[] = [];
      res.data.forEach((row: any) => {
        data.push(
          <Option value={row.symbol}>{row.symbol + ": " + row.name}</Option>
        );
      });
      return data;
    })
    .then((data) => {
      console.log(data);
      callback(data);
    })
    .catch((err) => console.error(err));
};

May I ask why does the options not appear until after I clear the text that I entered in the search box?

Add optionFilterProp="children" as Select component's props.

Turns out filterOption={false} needs to be added to the Select component, i.e. the following actually works:

<Select
  showSearch
  value={symbol}
  onSearch={handleSearch}
  onChange={handleChange}
  filterOption={false}
>
  {searchResults}
</Select>

The default value for filterOption is set to true.
