Ariadna fastAPI how to parse GraphQL request

Question

Here is my API:

app = FastAPI()
app.add_middleware(CORSMiddleware,
                   allow_origins=['*'],
                   allow_credentials=True,
                   allow_methods=["*"],
                   allow_headers=["*"])

type_defs = load_schema_from_path("schema.ql")
schema = make_executable_schema(type_defs, query,
                                snake_case_fallback_resolvers)
# print(dir(schema.__dict__))
print(schema.__dict__)
app = CORSMiddleware(GraphQL(schema, debug=True),
                     allow_origins=['*'],
                     allow_methods=("GET", "POST", "OPTIONS"))

Is there a way to parse an Ariadne graphql request into python key values at the middleware / router level in this file?
