It is in possible to add family members. Nest redirect to Google Home and Google home doesn't have any features to ad a family member. Also I set up the cameras for people who can't do it themselves but don't want take space of their family members allowed to use it. There should be a option to for unskilled users to hire an "admin" to set up and maintain Nest and Google devices but be sort of on call not be owner, user or member of the family.
Thanks for your assistance, davidking.
Thanks for sharing your thoughts about this. No worries, we'll figure this out together. You can follow the steps below to add a family member in the Google Home app:
You can have up to 6 members in a Google Family Group. The person you invite should receive an email with instructions.
I hope this helps.
