Select Settings Settings.
Under “Search and Assistant”, select Google Assistant.
Select Google Assistant settings.
Under “Devices”, select Chromebook.
Next to “Access with Voice Match”, tap the toggle to turn voice recognition on or off.
However, at that final step, after selecting the Chromebook, I get no "Access with Voice Match" option.
The microphone on the chromebook works ok and I can perform google searches by clicking on the microphone icon first, but the device fails to respond to "Ok Google" or "Hey Google"
