New Nest camera on trial subscription

[Riffer]

I purchased a new Nest indoor camera for my summer home. It came with a free Nest Aware  trial subscription. The trial runs out in 4 days. I have another Nest Aware + account for the cameras at my other home that just renewed. How do I transfer the new camera to my existing Nest Aware + account?

A Nest Aware subscription applies only to cameras and doorbells in the same Google Nest "home/structure" on the same Wi-Fi network on the same Google Account.
