wait for Listview loaded

I think you can use ImageRepository Class.

Create the image from screen with loading spinner (If the spinner is moving, the photo may not be recognized, if it is moving, do only part of the loading message)

After that check in script for this image. Take a look at this one:

if(ImageRepository.obj.obj.Exists(Sys.Desktop));
    
function waitUntilObjectExist(obj, counter) {
  var counter = counter || 60;
  for (var i = 1; i <= counter; i++) {
    if (obj.Exists == true) {
      aqUtils.Delay(1000);
    } else {
      break;
    }
  }
}
