React - Upload avatar to firebase

[Artur]

Good afternoon, I can’t figure out how to upload a photo (avatar) to firebase, but so that the avatar for each user is different and saved at each user login. User registration via firebase Authentication

const [user, loading] = useAuthState(auth);
  const [image , setImage] = useState("");
  const storage = getStorage();

//upload function
  const upload = ()=>{
    const storageRef = ref(storage, `usersAvatar/${image.name}`);

    if(image == null) return;
    uploadBytes(storageRef, image).then(() =>{
      getDownloadURL(storageRef).then((url) => {
        setUrl(url);
      })
    })
  }


// return
<input type="file" onChange={(e)=>{setImage(e.target.files[0])}}/>
<button onClick={upload}>Upload</button>
