Problems with custom components in Aurora

Code:

import type { CustomComponentProps } from 'aurora/externalContext';
import React from 'react';
const ExampleComponent: React.FC<CustomComponentProps> = ({ auroraContext }) => {
  const { components, utils } = auroraContext;
  const { i18n } = utils;
  const { Panel, PanelBody } = components;
  return (
    <div>
      <Panel>
        <PanelBody>
          <p>{i18n.formatMessage('panel.title')}</p>
        </PanelBody>
      </Panel>
    </div>
  );
};
export default ExampleComponent;
Would be grateful for any help, thanks!
