Pro Power Kit V3

Hi I am based in the UK. I bought the Spare Parts kit which includes the Power Kit V3 to connect the Honeywell D117 wired mechanical doorbell chime to my Ring Video Doorbell. However the Ring customer service agent provided an installation diagram which is for 2 doorbells (front and rear) and I have no idea how it should be wired. Is there a correct diagram for my setup which is: 1 Doorbell, 1 Mechanical Chime, 1 Ring Transformer and Echo Show? (PS Echo show is just for receiving wi-fi doorbell alerts through the Ring app and doesn't need wiring)
