code: function getInStory(selector) {
    cy.get('#storybook-preview-iframe').then($iframe => {
      const doc = $iframe.contents()
      return cy.wrap(doc.find(selector))
    })
  }
docs: because storybook loads our story in an iframe, we have to get that iframe and select items inside there. Learned this from https://medium.com/@mtiller/testing-react-components-using-storybook-and-cypress-1689a27f55aa
