                type="button"
                className="btn btn-lg btn-link"
                data-dismiss="modal"
              >
                Cancel
              </button>
              <button
                type="button"
                className="btn btn-lg btn-primary"
                data-dismiss="modal"
              >
                Confirm
              </button>
            </div>
          </div>
        </div>
      </div>

{/* modal end */}

and this is the button i have so that the modal appears :

 <button
        type="button"
        className="btn btn-lg btn-primary"
        data-bs-toggle="modal"
        data-bs-target="#small_modal"
        
      >
        Small modal
      </button>

i dont know why it is not working, do i need to write something else ?
i added the bs on data-toggle and data-target because i saw online it is needed, but it still didnt work

>Solution :

You can use the below approach to achieve this. Adding custom onClick events on buttons.

 <button
      type="button"
      className="btn btn-lg btn-link"
      data-dismiss="modal"
      onClick={() => {
              document.getElementById('small_modal').style.display = 'none';
              document.getElementById('small_modal').style.opacity = 0;
       }}>
           Cancel
     </button>

Full code :

import "./App.css";

export default function App() {


  return (
    <div className="App">

{/* modal start */}
       <div
        id="small_modal"
        className="modal fade"
        role="dialog"
        aria-labelledby="mySmallModalLabel"
        aria-hidden="true"
      >
        <div className="modal-dialog modal-sm">
          <div className="modal-content shadow-max">
            <div className="modal-header">
              <h3 className="modal-title" id="exampleModalLabel1">
                Modal title
              </h3>
              <button
                type="button"
                className="close icon"
                data-dismiss="modal"
                aria-label="Close"
                onClick={() => {
                  document.getElementById('small_modal').style.display = 'none';
                  document.getElementById('small_modal').style.opacity = 0;
      
              }}
              >
                close
              </button>
            </div>
            <div className="modal-body">

              }}
              >
                Cancel
              </button>
              <button
                type="button"
                className="btn btn-lg btn-primary"
                data-dismiss="modal"
              >
                Confirm
              </button>
            </div>
          </div>
        </div>
      </div>

{/* modal end */}
     <button
        type="button"
        className="btn btn-lg btn-primary"
        data-bs-toggle="modal"
        data-bs-target="#small_modal"
        onClick={() => {
            document.getElementById('small_modal').style.display = 'block';
            document.getElementById('small_modal').style.opacity = 1;

        }}
          
      >
        Small modal
      </button>
    </div>
  );
}

Although it will fix the issue but I’ll recommend to use react-bootstrap library for this. Using React Bootstrap you’ll be able to do to the same thing in much easier and simpler way.
