How to quickly add a Modal?

Hi!
I want to add a confirmation modal to the button Hangup


I found the action to the button, but a modal doesn’t appear when I add it.
I added:
import React, { useState } from ‘react’;
import ModalDialog, { ModalTransition } from ‘@atlaskit/modal-dialog’;
and
image
What I can do?

Ya está hecho, tienen muchos archivos para poder hacer esa implementación, pero funcionand de maravilla :smiley:
