SOLVED: Next Experience Developer Tools won't open

[aasch]

EDIT with solution:
The extension seems to have been installed correctly.
I just had to open the Chrome dev tools and look for the Inspector/Profiler tab. I hadn't done that, because clicking on the extension icon seemed broken so I stopped looking any further.
(I'm a fool :D)

Hi,

I wanted to the try the Next Experience Developers Tools on my PDI, but they don't open for me.
It's always just showing a small white square, no matter what I do or how long I'm loading, see attached screenshot.

Am I doing it wrong?

I've followed the Guide on the "Getting started" page, downloading and installing the extenson from the Chrome store.

Additional info:

• Chrome version: 137.0.7151.104 (64 bit), freshly installed yesterday
• NEDT version: 3.6.2
• PDI SN release: Yokohama
