Bootstrap5 modal not displaying in React.js after clicking on the button

Question

I am using bootstrap5 to React. I successfully installed the bootstrap5 in React. Now I have to show the modal on my page so I added a button and modal code on my page.

Below is the code I am using for the modal. Now I click on the button then nothing is working. I am not getting my modal.

What is the issue here?

import React from "react";

function addEmployee(){
    return(
<div className="addEmployee">
<button type="button" className="btn btn-primary" data-bs-toggle="modal" data-bs-target="#staticBackdrop">Add Employee</button>

<div className="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabIndex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
  <div className="modal-dialog">
    <div className="modal-content">
      <div className="modal-header">
        <h5 className="modal-title" id="staticBackdropLabel">Modal title</h5>
        <button type="button" className="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div className="modal-body">
        ...
      </div>
      <div className="modal-footer">
        <button type="button" className="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" className="btn btn-primary">Understood</button>
      </div>
    </div>
  </div>
</div>


</div>

    )
}
export default addEmployee;

Bootstrap 5 no longer depends on jQuery so you don't need a 3rd party library library like react-bootstrap to use Bootstrap in React. For example you can use the data-bs- attributes in the markup, or create a functional component for the Bootstrap modal with methods to show/hide the modal...

function ModalExample() {
    const modalRef = useRef()
    
    const showModal = () => {
        const modalEle = modalRef.current
        const bsModal = new bootstrap.Modal(modalEle, {
            backdrop: 'static',
            keyboard: false
        })
        bsModal.show()
    }
    
    const hideModal = () => {
        const modalEle = modalRef.current
        const bsModal= bootstrap.Modal.getInstance(modalEle)
        bsModal.hide()
    }
    
    return(
        <div className="addEmployee">
            <button type="button" className="btn btn-primary" onClick={showModal}>Add Employee</button>
            <div className="modal fade" ref={modalRef} tabIndex="-1" >
             <div className="modal-dialog">
                <div className="modal-content">
                  <div className="modal-header">
                    <h5 className="modal-title" id="staticBackdropLabel">Modal title</h5>
                    <button type="button" className="btn-close" onClick={hideModal} aria-label="Close"></button>
                  </div>
                  <div className="modal-body">
                    ...
                  </div>
                  <div className="modal-footer">
                    <button type="button" className="btn btn-secondary" onClick={hideModal}>Close</button>
                    <button type="button" className="btn btn-primary">Understood</button>
                  </div>
                </div>
              </div>
            </div>
        </div>
    )
}
