Cannot connect Google Hiome with 3rd party application - LG Thinq/Xiaomi Home

Hi Everybody. 

I am new Google Home user. 

I have a problem adding a third-party app to Google Home. I would like to control Xiaomi/LG devices in Google Home.

I follow the instructions and log in to LG or Xiaomi, but nothing happens - a blank page with an inactive link appears
(nothing happens when I click on it).

Below are the steps I took on the screenshots.
