SketchUp Pro 2020: where has the Extensions menu gone?

I installed 2020 today, to find I have to install every extension manually…
But then I can’t find the main extension menu anymore. How can I get it back? Or should I be running my extensions from other places now?

The Extensions menu only appears when you have installed an extension that places commands into it. Many extensions use other menus instead.

Thanks. :slightly_smiling_face:
