Sadly could not get it to work with Chrome and I was hoping this could be used with Brave Browser but it doesn't seem to function there either

Works well so far. Doesn't handle other YT chat extensions very well. For example HyperChat breaks translation completely. Would be perfect if these two could sort it out.
