Language Reactor dosen't work on my chrome

It works perfectly when I watch Netflix on my window edge, but in chrome, there is no button or anything. Just dosen’t work… I don’t know why, but same thing happens in youtube too.

I deleted, redownload, even turned off and on my lap top but it still doesn’t react on chrome. Is there anything that I can do more to fix this problem? I checked everything as I can see
