@NiyiredC With the universal web adapter, you cannot interrogate that control as it is not a web page. You'd likely need to use screen OCR to check for it. Below is an article on that feature. You'll need to make sure that OCR Essentials is installed. That can be downloaded from the Pega digital delivery website along with Runtime or Studio.
I would also suggest that you grab the latest version of Pega Robotics Runtime and Studio. The version you are using (8.0.2025) is close to end-of-life and came out over three years ago.
You might also take a look at the new V21 version as that is being released very soon and will have lots of new feature available to developers. A preview release is available and can be installed alongside the latest 19.1 versions. It may work with 8.0 SP1, however I suggest you upgrade to at least 19.1 first.
