Ring Doorbell Pro and Nicor 18888 Chime/transformer issues

All, I'm close to returning ~$1K worth of Ring products to Ring. This is beyond frustrating. I just moved into a newer house (6 years old) and am trying to install the Ring doorbell pro. We currently have a Nicor 18888 doorbell chime, which is a chime and transformer combo. I have two, one upstairs and one downstairs. I learned that the Nicor 18888 is not compatible. Therefore, I purchased a transformer from Amazon ([https://www.amazon.com/gp/product/B07GND8RMQ/ref=ppx\_yo\_dt\_b\_asin\_title\_o01\_s00?ie=UTF8&psc=1](https://www.amazon.com/gp/product/B07GND8RMQ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1)) and installed it. As soon as i turned the power on, it continually chimed as if someone was laying on the doorbell. Then after speaking with Ring support (not helpful), they said that i have another transformer somewhere in the house because the Nicor 18888 is not a transformer. They are mistaken. I called the manufacturer that built my house and they confirmed that my house does not have any additional transformers anywhere. At this point, I am willing to bypass the entire chime and despite my frustration, purchase additional Ring chimes to use for sound. However, even with completely removing the Nicor 18888, i still can't get it to connect! I called Ring again and they said that i need to hire an electrician or purchase the plug in power supply. NOPE. Wife does not want me making holes in the house and I’m tired of buying more stuff to get this to work. The main reason i purchased Ring over competitors was due to their alleged ease of install. Can someone please post a picture or provide instructions on how to get this thing to work (and please not the same diagrams from Ring that I’ve received each time I call them)? See pictures of what I’m working with. Any assistance is appreciated.
