Unable to add Google Cam Outdoor Battery to Nest App

[carlosag012]

I just bought a Google outdoor camera (battery) and a google door bell 2nd Gen, and I can't add any to the Nest App. I tried:
- Adding from the Nest App. 

   -> This option says I have to add them through the Google Home app. So I did.

- Once setup, I looked for settings, but I was unable to find anything that would sync the devices with the Nest App. 

- Google search, the assistant gave me multiple options to follow, they didn't work, most of the time the settings were incorrect after the 2nd step. 

- Contacted Google support over the phone, when I got to the Google Nest devices (2-2-4) then it say the number is unavailable. 

- Last, tried signing out and back in from the Nest App account, but this didn't help either. 

Any advice on what to do next? I can't believe these are partner companies and their products only work one way?

Google Nest's 2nd gen cameras and doorbells get installed ONLY in the Google Home app and NOT in the Google Nest app. We discovered this when we bought a battery camera in Sept. 2021, and have been using 2 apps ever since.

It is now possible to "transfer" all 1st gen cameras and doorbells from the Google Nest app to the beta "Public Preview" version of the Google Home app (https://www.googlenestcommunity.com/t5/Blog/Expanded-support-rolling-out-all-Nest-Cams-can-transfer-...). We are not using the "Public Preview" version (it has been in "Public Preview" status since November 2022) and are NOT "transferring" our 1st gen cameras and doorbells because the Google Home app still lacks many Nest app functions (https://support.google.com/googlenest/answer/13038234#zippy=%2Cnest-app-only-features).

P.S. You CAN view all of your 1st and 2nd gen Google Nest cameras and doorbells on the "Public Preview" home.google.com website.  (That's also been in "Public Preview" status for a couple of years.)
