How to setup Chrome Remote Desktop host

[DaniDipp]

I have successfully set up the container and connected to it via VNC.
I have downloaded the Chrome Remote Desktop extension from the Chrome Web store and logged into https://remotedesktop.google.com with my Google account.

How do I now authorize it for remote connections?
The readme says "My Computers > Enable Remote Connections" but I can't find anything like that on the crd website.
I'm able to generate a one-time "Remote Support" code that allows me to connect via CRD but it would require generating a new code for every session which defeats the point. Google seems to want me to "Set up via SSH" which give me a .msi or .deb file

How do I proceed?
