    Difference from asyncio.run():
    - asyncio.run() cancels all tasks when `main` is completed.
      any tasks created using `asyncio.create_task()` will hence be cancelled.
    - run_with_wait() waits for all tasks to be completed using
      `run_until_complete()` and `asyncio.tasks.gather()`

My Approach: React Context with a custom useError hook

Even though React provides Error Boundaries API, it is not a good candidate, nor is relevant for handling GraphQL query errors.
