Can't open the extension on Brave/Chromium

[serpro69]

It seems like this extension is abandoned? But maybe someone else can give me a tip on how to make it work.

The problem I have is that the extension window just won't open in Brave (MacOS). The extension version says 2.0.2, so I'm wondering if it may have some bug, or it's too old for newer chromium versions, or something in between?

I've tried on firefox (librewolf, to be more precise), and the extension there works fine (it's version 1.6.0 though, which is the latest version currently available in firefox extensions page)

Anyone knows how this could be fixed?
