I am new to automation testing and currently learning Cypress.io

I am using the Emirates website as an example and written the following code to select accept when the privacy screen pop-up window appears, but my code seems to be timing out and failing:

Can you please tell me what I am doing wrong, and explain why did behaviour occurs in cypress and how to resolve it.

Appreciate the support.

/// <reference types="cypress" /> 

import Homepage from './pageObjects/Homepage.cy.js';

describe('Basic Tests', () => {

  const homepage = new Homepage();

  beforeEach(() => {
    cy.log('Opening Emirates URL');
    homepage.visit();
    homepage.verifyTitle(homepage.EXPECTED_TITLE);
    cy.wait(3000);
  });

  it('Privacy Pop-up', () => {
    cy.get('button[@id="onetrust-accept-btn-handler"]')
      .click()
  
    cy.wait(5000)
  });
