Wiring to get power from door chime

Help please.
This is the picture of the transformer in my existing door chime.
Which 2 wires do I connect to use this to power my wired ring doorbell please?

Hi @rtigerc. Can you please confirm which model of Video Doorbell you are trying to install? The model name will be on the original packaging and on the back of the device itself (Video Doorbell Wired, Video Doorbell Pro). This information is important as the installation instructions can vary from one Doorbell model to the other.
