problem with Remote Control Browser settings

Hi. I recently started with libreelec. i successfully installed leia and chrome on a laptop. i made kore work, but kore doesn't work in chrome.. I installed "Remote Control Browser", but I can't get it to work, in the configuration menu, I enter the browser's address, but obviously I'm doing something wrong .. any help?

Thanks in advance
Alejandro

Hello!! I had already activated the web service, and kore works fine in the rest of kodi, but it responds to no function in chrome .. I tried with yatse, but it doesn't respond when opening chrome either .. there is some other add-on to be able to control chrome from kore ? thank you!
