Do I need to unmount nest Doorbell to get QR code

[AngelaAmato87]

I have a nest Doorbell that is already mounted from the previous owner.  I cannot take off the doorbell to gain access to the QR code.  How do I link it to my google home account without dismounting the doorbell

Same question here. I would imagine this is a common problem. It is nonsense to have to rely on scanning a QR code, especially once it's mounted.
