title: Property does not exist on type 'JestMatchers '
body: <p>I'm working with an app where I want to have installed jest and cypress for testing purposes. I have my jest test that run ok and everything is fine with that, then I installed cypress by executing this command</p>
  <pre><code> yarn add cypress @cypress/react @cypress/webpack-dev-server
  </code></pre>
  <p>And I have my test in Cypress that runs ok whenever I try them using</p>
  <pre><code>yarn cypress open-ct
  </code></pre>
  <p>But the thing is, that Chai assertions works well in the test but show errors in my IDE</p>
  <p>My dummy test</p>
  <pre><code>it('Test test and onClick', () =&gt; {
    let clicked = false
    const onClick = () =&gt; (clicked = true)
    mount(&lt;Button text=&quot;Random text&quot; onClick={onClick} /&gt;)
  
    cy.get('button').should('have.text', 'Random text')
    cy.get('button')
      .click()
      .then(() =&gt; {
        expect(clicked).to.equal(clicked)
      })
  })
  </code></pre>
  <p>and the error shown:</p>

  <p>I have tried to follow some guides I saw on the Internet but I'm missing something because my IDE (Webstorm or Visual Studio) only suggests me Jest assertions not Chai's, and if I use Jest assertion I got this error while running Cypress</p>
  <p>Changing the test assertion to this:</p>
  <pre><code>expect(clicked).toEqual(clicked)
  </code></pre>
  <p>shows this error:</p>

  <p>I don't really care if I have to use Jest or Chai assertions as long as this works. My preference will be Chai's because are the ones that works within Cypress, but right now, I only wanted that to don't show an error in my IDE or in Cypress.</p>
  <p>Thanks!</p>
