OK Google - Retrain Voice Model & From Any Screen switch greyed out

[Deventer]

My wonderful Galaxy 7 is now nine days old but I can still not retrain the voice model. The option is always greyed out. At the moment Ok Google will respond to anybody; man, woman or child.
When I follow the alternative path, via General Management, the From Any Screen option does not switch on.

There must be a way to overcome this but my internet searches have not yet revealed it. I do hope that you can help.

You have to enable "OK Google" detection first, then the two items you mention will un-grey. (is that a word? )

I'm not sure where that is located in your Settings.

Long hold your HOME key until the Google Assistant opens. Click on the blue circle in upper right. Click on the 3 dots on upper right. Go into Settings. Under Devices click on Phone. Go into OK Google detection. Good luck from there!

Thank you both for your suggestions. No success yet and CWinkler, you leave me with another mystery as prolonged pressure on the home button does not produce any assistant with a blue disc in the upper rh corner.

Perhaps this will help: "Ok Google" voice command not working on Samsung Galaxy S7

This is the screen I get when long pressing the HOME button. Do you not get that?

Sorry for the delay, couldn't figure out how to attach screenshot through the app. Had to wait until I was back on computer.
