Extra actions should be placed at corner of drawer in Ant Design, you can using extra prop for that.

import React, { useState } from 'react';
import { Drawer, Button, Space, Radio } from 'antd';
import { DrawerProps } from 'antd/es/drawer';
import { RadioChangeEvent } from 'antd/es/radio';

const App: React.FC = () => {
  const [visible, setVisible] = useState(false);
  const [placement, setPlacement] = useState<DrawerProps['placement']>('right');
  const showDrawer = () => {
    setVisible(true);
  };
  const onChange = (e: RadioChangeEvent) => {
    setPlacement(e.target.value);
  };
  const onClose = () => {
    setVisible(false);
  };
  return (
    <>
      <Space>
        <Radio.Group value={placement} onChange={onChange}>
          <Radio value="top">top</Radio>
          <Radio value="right">right</Radio>
          <Radio value="bottom">bottom</Radio>
          <Radio value="left">left</Radio>
        </Radio.Group>
        <Button type="primary" onClick={showDrawer}>
