That 'Thanks' can be clicked? That means it is a kind of button. You have to enable Accessibility service for automagic to make it work. It is at the Preferences.
First, to check the appearance of it, you can use Trigger : UI event, leave that window open, navigate to the app and wait for the 'Thanks' to appear. After it appear, quickly switch back to automagic and tap recent events, to check for that 'Thanks'. Choose that, and that will be the trigger.
To click it, you have to check the component Id using Action : Control UI. Use the Show overlay control and navigate to the app that pop that button. Wait until it appear and press info, tap that box surrounding the "Thanks", choose clickById(). Back to Automagic, you can paste the click script in the Control UI.
Enable the flow, and everytime that 'Thanks' appear in that app, automagic will automagically click it.
If it didn't work, you should screenshot it (when the thanks appear), edit the screenshot to hide any sensitive information and post it here. Or if clickById() didn't appear on choice list, you can try to use click().
@Martin : I think this Event UI / Control UI deserves its own page of example tutorial, from choosing and acting on the components, until detecting available text in certain app. I have typed some already, but of course can't cover as detail as the one who create it
