How to use the @storybook/api.useChannel function in @storybook/api

const SignInPanel = () => {
  const value = useParameter(PARAM_KEY, null);

  const [state, setState] = useState(Providers.globalProvider.state);

  const emit = useChannel({
    STORY_RENDERED: id => {
      console.log('storyRendered', id);
    },
    [GETPROVIDER_EVENT]: params => {
      emitProvider(state);
    }
  });

  const emitProvider = loginState => {
    emit(SETPROVIDER_EVENT, { state: loginState });
  };

  Providers.onProviderUpdated(() => {
    setState(Providers.globalProvider.state);
    emitProvider(Providers.globalProvider.state);
  });

const ViewportTool = () => {
  const [role, setRole] = useAddonState(ADDON_ID, 'myra_range_officer')

  const emit = useChannel({
    [STORY_RENDERED]: () => {
      setTimeout(() => {
        emit('role/change', role)
      }, 100)
    }
  })

  const handleChange = e => {
    setRole(e.target.value)
    emit('role/change', e.target.value)
  }

  return (

const Editor = ({ api }: { api: API }) => {
  const emit = useChannel({});
  const story = useCurrentStory();
  const storyId = story && story.id ? story.id : '';
  const [initialCode, setInitialCode] = useEditor();
  const [metaData, setMetadata] = React.useState(null);

  let previousSource = '';

export const Panel = () => {
  const [results, setState] = useAddonState(ADDON_ID, []);
  const emit = useChannel({
    [EVENTS.RESULT]: (newResults: Results) => setState(newResults),
  });

export const CoverageTool: React.FunctionComponent<{}> = () => {
  const [active, setActive] = useState(true);
  const icon = active ? 'eye' : 'eyeclose';

  window.getStoryColor = (storyId: string) => getColor(storyId, active);
