How to handle response middleware?

[subokita]

While doing normal REST request, the following code works without issue however, when it comes to GraphQL, it seems like the middleware only handles 'request' but not 'response'

@app.middleware('response')
async def print_on_response(request, response):
	print("I print when a response is returned by the server")

Anyone knows if this is a missing feature, bug, or am I the one who's missing something?
