YouTube / Web Browser plugin?

Is there anything like a YouTube or Web Browser (Chrome) plugin available for OpenATV for a Zgemma H7S?

It looks like a YouTube add on is available through Kodi, but you need to apply Personal API keys....

It seems I got an API key several years ago but never used it....

Is there any way to get YouTube to read it from a file. I think it will take quite a while (after numerous errors) trying to type it into Kodi.
