How to set up Unattended Access on a Chromebook Chrome OS?

mk71

Good morning. Recently purchased a Chromebook for mum. I had previously setup unattended access to her old windows pc, from my own windows based pc, to offer her tech support simply by double clicking on her TV ID when she was online. Worked like a charm each time she had pc issues. Her old pc gave up and now she has a Chromebook. Now with Chrome OS I'm unable to set Unattended Access. What I'm trying to avoid, is having mum give me a code each time. Is there a way to set up unattended access from my win10 pc to her chrome OS? Thanks.
