how to structure the app to re-use rate liming in multiple routers?

[encryptblockr]

lets say i have folder structure

app/
     |── app.py
     |── users/
                  |── router.py
                  |── tasks.py
     |── orders/
                  |── router.py
                  |── tasks.py

lets say the app.py has the following

from fastapi import FastAPI, Request

from app.users import router as user_router
from app.orders import router as order_router

app = FastAPI()

app.include_router(user_router.router, tags=["users"])
app.include_router(order_router.router, tags=["orders"])

if __name__ == '__main__':
    app.run()

how do i setup asgi-ratelimit so i can re-use across all the router.py files?
