How to use Xbench on Phrase with macOS

Hi!
I’m new here, and I would like to ask you guys how to run Xbench on Phrase.
I have several accounts of Phrase for various clients, those account credentials are given by them.
The extension is installed in Chrome, and the icon appears at the top right of the window. However, clicking the icon doesn’t activate anything; no Xbench window opens.

What is the next step to run Xbench?

Thanks in advance,
Pinetree

Xbench is a Windows application. Check the following forum post.
