[Python] FastAPI is not returning cookies to React frontend

Why doesn't FastAPI return the cookie to my frontend, which is a React app?

Here is my code:

@router.post("/login")
def user_login(response: Response,username :str = Form(),password :str = Form(),db: Session = Depends(get_db)):
user = db.query(models.User).filter(models.User.mobile_number==username).first()
if not user:
raise HTTPException(400, detail='wrong phone number or password')
if not verify_password(password, user.password):
raise HTTPException(400, detail='wrong phone number or password')


access_token = create_access_token(data={"sub": user.mobile_number})
response.set_cookie(key="fakesession", value="fake-cookie-session-value") #here I am set cookie
return {"status":"success"}


When I login from Swagger UI autodocs, I can see the cookie in the response headers using DevTools on Chrome browser. However, when I login from my React app, no cookie is returned. I am using axios to send the request like this:

await axios.post(login_url, formdata)
