How to use the @ant-design/icons.createFromIconfontCN function in @ant-design/icons

/* eslint-disable camelcase */
import React from 'react';
import AntdIcon, { createFromIconfontCN } from '@ant-design/icons';

import { withThemeSuffix, removeTypeTheme, getThemeFromTypeName } from './utils';
import warning from '../../../../components/_util/warning';

const IconFont = createFromIconfontCN({
  scriptUrl: '//at.alicdn.com/t/font_1329669_t1u72b9zk8s.js',
});

const OldIcon = props => {
  const { type, theme } = props;
  let computedType = type;
  if (theme) {
    const themeInName = getThemeFromTypeName(type);
    warning(
      !themeInName || theme === themeInName,
      'Icon',
      `The icon name '${type}' already specify a theme '${themeInName}',` +
        ` the 'theme' prop '${theme}' will be ignored.`,
    );
  }
  computedType = withThemeSuffix(removeTypeTheme(computedType), theme || 'outlined');

export const Rcon = forwardRef((props: IProps, ref: any) => {
  // ANTD OFFICIAL ICON --> '//at.alicdn.com/t/font_1329669_t1u72b9zk8s.js'
  const CustomIcon: any = createFromIconfontCN({ scriptUrl: localIconfont, extraCommonProps: { ...props } });

  return (
    
  );
});
