I have some data and form inputs, I need to prefill the existing data in the fields and when click on edit I like to edit the data and submit it to the state on button click

const data = {
  name: "nazar",
  email: "[email protected]",
  phone: 123456789
};

const [ editData, setEditData ] = useState()

function handleEdit(){
  
}

function handleSubmit(){
  
}
<form onChange={handleEdit}>
    <input type="text" name='name'/><button>Edit</button><br/>
    <input type="text" name='email'/><button>Edit</button><br/>
    <input type="text" name='phone'/><button>Edit</button><br/>
    <button type='submit' onSubmit={handleSubmit}>Submit</button>
</form>

 // declare your data as initial state
 const [data, setData] = React.useState({
    name: 'nazar',
    email: '[email protected]',
    phone: 123456789,
  });

  // handle on change according to input name and setState
  const handleChange = (e) => {
    setData({ ...data, [e.target.name]: e.target.value });
  };

  const handleSubmit = (e) => {
    e.preventDefault()
    // take data to submit
  };
  return (
    <div>
      <form onSubmit={handleSubmit}>
        <input
          type="text"
          name="name"
          value={data.name}    // inject state correspond to input and so on
          onChange={handleChange}
        />
        <button>Edit</button>

        <input
