You Need to use State here is the working-class component example of a model. if you are using functional components then use useState() hook instead of this.setState() method

    import React from "react";
        
        export default class AddNewList extends React.Component {
          state = {
            showModal: false
          };
        
          closeModal = () => {
            this.setState({ showModal: false });
          };
        
          onSave = () => {
            console.log("i saved the data.");
            this.setState({ showModal: false });
          };
          verifyOtp = () => {
            //your success value
            if (true) {
              this.setState({ showModal: true });
            }
          };
        
          render() {
            return (
              <>
                <div>
                  <button onClick={this.verifyOtp} className="btn btn-primary btn-lg">
                    Open Modal
                  </button>
                </div>
                {this.state.showModal && (
                  <div className="" id="addnewlist">
                    <div className="modal-dialog">
                      <div className="modal-content">
                        <div className="modal-header">
                          <h4 className="modal-title"> Model Header</h4>
                        </div>
        
                        <div className="modal-body">
                          test
                        </div>
        
                        <div className="modal-footer">
                          <button
                            type="button"
                            className="btn btn-danger"
                            data-dismiss="modal"
                            onClick={this.closeModal}
                          >
                            Close
                          </button>
                          <button
                            type="button"
                            className="btn btn-outline-success"
                            onClick={this.onSave}
                          >
                            Save
                          </button>
                        </div>
                      </div>
                    </div>
                  </div>
                )}
              </>
            );
          }
        }

Skeleton for the functional component

import React, {useState} from 'react'
    const [showModel,setShowModel] = useState(false);
    function AddNewList (){
    closeModal = () => {
            setShowModel(false);
                  };
        
          onSave = () => {
            setShowModel(false);
          };
          verifyOtp = () => {
            //your success value
            if (true) {
              setShowModel(true);
            }
          };
    return render();
    }
