react CSS form validation

While making a form on react I downloaded some libraries and copied some example I ultimately went with one I made my self but now my entire project has this validation that will stay no matter what I put in the project. Every time I click a button I get a tooltip and I have no idea how to control it.

Here is my code

import React, { useEffect } from 'react';
import axios from 'axios'

const FormRequest = () => {

   
    const formSubmitHandler = () => {
        
      console.log()
        }

    return (
        <div  >
            <div >
                <div >
                    <div>
                        <div>
                            <div></div>
                            <div></div>
                        </div>
                        <div>
                            <div></div>
                            <div></div>
                            <div></div>
                        </div>
                    </div>
                    <div >
                        <div >
                            <div >
                                <span>CONTACT</span>
                                <span>US</span>
                            </div>
    
                        </div>
                        <div >
                            <form  onSubmit={(formSubmitHandler)}>
                                <div >
                                    <input

                                        onChange={''} value={''} required />
