Good morning - I wonder if anyone can help. I am trying to use custom widgets in Web App Builder. I have downloaded several custom widgets from this site and followed the steps listed below. When I go into Web App Builder and try and add the widget, I can see the widget icon under the 'custom' tab - but when I select the icon it does not let me click OK to then begin using the tool. Any help would be greatly appreciated.
