Using React component in plugin written in Angular

I’ve read below information at https://github.com/grafana/grafana/wiki/Frontend:-Code-structure,-architecture-and-plans-for-the-future

Currently, some whole pages are written in React and some components are written in react. It is easy to use a react component in an angular component.

Could somebody give me example how to do it?
For example - I want to use TimePicker (https://github.com/grafana/grafana/tree/master/packages/grafana-ui/src/components/TimePicker) in my Angular plugin.
