Escaping a 'Your Apple iPhone has been hacked' pop-up on Duck Duck Go

got this message: Your Apple iPhone has been hacked. All operations on your device are being tracked by the hacker. Immediate action is required!

but not able to escape the page, go back or clear the tabs

occurred using Duck Duck Go

what is the way to get out of it? close the app and delete it?

obviously not going to hit any of the options the pop up provides
