It is a great tool

This is a great tool but somehow how it stopped working in latest chrome and the error in the console is:
(index):1 Error in event handler: TypeError: Cannot read properties of undefined (reading 'nodeName2')
at Object.CreateCLSDiv (chrome-extension://jbbeihojggidiclbcneckhcblilapahn/cls.js:59:49)

No Visualization on new chrome

Similar to the other recent problems reported, I'm unable to see the visualization from this plugin anymore. It's a shame because this is the only tool I've been able to find that can accomplish that - possible to get an update?

CLS in Viewport

Hello,
thanks a lot for that great little tool.
But I think it only shows the CLS in the viewport of the page and not below the fold - right?
Thanks and regards
Roland
