Yodlee UI closing issue

Question

I'm using the yodlee for some developing purposes for my ongoing project with nuxtjs 2.I cannot close the rendered Yodlee UI by clicking the close button in top of the yodlee page. However, the back button is working as expected after selecting a bank.

The initial page

After selecting a bank and its working(the go back which is in the top of the left side)

Even no console errors and I just tried with the class of the a tag related to the button below

mounted() {
  let fastLinkCloseBtn = document.getElementsByClassName(
    'icon-link close-icon'
  )
  if (fastLinkCloseBtn) {
    console.log('working')
    fastLinkCloseBtn.onClick = window.fastlink.close()
  } else {
    console.log('not working')
  }
},
