Un middleware no tiene que estar hecho para FastAPI o Starlette para funcionar, siempre que siga la especificación ASGI.

En general, los middlewares ASGI son clases que esperan recibir una aplicación ASGI como primer argumento.

Entonces, en la documentación de middlewares ASGI de terceros probablemente te indicarán que hagas algo como:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()
