Nest integration Help - adding another device to existing integration

Hey guys, hoping you can help. I set up the nest integration a while back and got the camera and thermostat on the dashboard.

Got the doorbell yesterday and trying to add this now.

Correct me where i go wrong, but ive gone to Devices&Services, the google nest integration and then add device.

Here it comes up with Google cloud Project Id and Device Access Project ID
Question where do i get those?

Because when i enter what i think i should be entering it takes me to my choose an account, i click on it and it keeps saying Something went wrong, please contact developer if it persists.
