Firebase storage delete image by downloadURL V9

I’m trying to delete an image from Firebase storage in React Native by downloadURL. Also i’m using web V9.
Writing down most essential chuncks of code:

import {
  deleteObject,
  getStorage,
  ref
} from "firebase/storage";

...
// DownloadURL
const photo = "https://firebasestorage.googleapis.com.... ";

const storage = getStorage();
...
const storageRef = ref(storage, photo);
deleteObject(storageRef)
  .then(() => {
    console.log("File deleted successfully");
  })
  .catch((error) => {
    console.log(error.message);
  });

My code is inspired from here and I got this error:

[Unhandled promise rejection: FirebaseError: Firebase Storage: The
operation ‘deleteObject’ cannot be performed on a root reference,
create a non-root reference using child, such as .child(‘file.png’).
(storage/invalid-root-operation)]
I’m little confused.
