Camera notifications option does not appear

[Timglo]

I have 2 nest doorbell cameras and an indoor wired camera. I can see all 3 cameras in the google home app but within the app only the indoor camera appears as an option to have notifications for. I used to only have the two doorbell cameras on the nest app, I’ve migrated to google from nest but can only get notifications for the two doorbell cameras via the nest app. I want notifications for all cameras via the google home app. How can I make the doorbell cameras appear in the camera notifications settings?

We've been using 2 app ever since purchasing an 2nd gen battery camera 3 years ago, the Google Nest app for our 1st gen cameras and doorbells and the Google Home app for our 2nd gen battery camera and 2nd gen indoor camera.  (We "migrated" our Nest Account to a Google Account in 2019 or 2020.)

If you want to get all of your notifications in the Google Home app, you'll have to sign up for the beta "Public Preview" version of the Google Home app (it's been "Public Preview" for over 2 years), and then you'll have to "transfer" each of your 1st gen doorbells from the Google Nest app to the Google Home app.  We haven't done that because there are still many Nest app functions that are missing from the Google Home app:
