Wiring Diagram for two Doorbells on one Chime (1st and 2nd Gen doorbells)

[Wheelski84]

I had two Nest Hello doorbells connected to one chime. One of the Nest Hello doorbells broke and needs to be replaced. I purchased a 2nd Gen Nest doorbell to replace the broken one. After purchasing, I noticed the wiring on the 2nd Gen Chime Connector is different from the Nest Hello. Is there a wiring diagram that shows how to wire a Nest Hello doorbell, AND a 2nd Gen Nest Doorbell to the same chime?

Thanks.

Google Nest does not seem to publish such a diagram, though I've seen other requests in this forum. You'll probably have to make sense out of it yourself, using the diagrams Google Nest DOES provide for the 2nd gen camera in the Help topic below. Note that the second diagram, "Two Nest doorbells, two chimes", is mislabeled and should say "Two Nest doorbells, one chime". (I've asked repeatedly that they correct the label.)
