You can use react bootstrap modal component here.

import React, {useState, setShow } from 'react'
import {Modal} from 'react-bootstrap';


const myModal = () => {

    //handeling the modal open & close
    const [show, setShow] = useState(false);
    const handleShow = () => setShow(true);
    const handleClose = () => setShow(false);


   

    return (
       
        <>
            //this the button that triggers the modal
            <button onClick={handleShow}> Show Modal </button>

        

            <Modal className="my-modal" show={show} onHide={handleClose}>

                <Modal.Header closeButton className="mymodal-head">
                    <Modal.Title className="mymodal-title"><h4>The Modal</h4></Modal.Title>

                </Modal.Header>

                <Modal.Body className="mymodal-body">
//add your input fields and labels here
                    <input/>
                </Modal.Body>

                <Modal.Footer className="mymodal-footer">
//add your submit button here
                    <button> submit </button>
                </Modal.Footer>

            </Modal>


            
        </>
  
    )
}

Hope this helps: Feel free to ask me if you have any issues with the modal :)
