An example route that makes use of dependent tokens.

Note that the Globus SDK is not an async library. That means that I/O happens in the thread that calls SDK methods. As far as the author of this comment understands about such cases, routes should not be async. Doing so would block the asyncio event loop when calling SDK methods, preventing other async tasks from executing concurrently. If a route makes both Globus SDK calls as well as calls to I/O heavy async function/methods, an alternative is to have an async route and use starlette.concurrency.run_in_threadpool() to call Globus SDK methods. Alternatively, it may be reasonable to provide async wrappers of Horizon/Globus functions/methods that automatically do this.

:param token: The bearer token supplied to the API. :return: A list of the groups that the user represented by the token belongs to.
