How do I wire Video Doorbell (1st gen)?

I have a few questions on wiring my ring video doorbell 1st gen. 1. I have a Byron 776 and was wanting the mechanical chime to work. I was told (by phone support) this wouldn’t work but just realised it’s showing on ring’s compatibility list as a tested and working chime. So can I get the chime to work? 2. When wiring where does the jumper cable go. Again I was told to fit the jumper cable to the same terminals as where my bell wire goes but it doesn’t work. I had to remove the jumper cable to get power to the doorbell 3. My jumper cable has a little resistor on it, is this correct? That’s what came in the box.  4. When wiring a 3 pin plug what amp fuse needs to be in the plug?
