How to use the mangum.protocols.http.ASGIHTTPCycle function in mangum

        if is_binary:
            body = base64.b64decode(body)
        elif not isinstance(body, bytes):
            body = body.encode()

        asgi_cycle = ASGIHTTPCycle(scope, is_binary=is_binary, logger=self.logger)

        response = asgi_cycle(self.app)
        return response
