Ring doorbell with Nutone direct wire, need help

Hi, our new house has a Nutone direct wire doorbell, which has an integrated transformer. I believe it's this one (https://www.broan-nutone.com/en-us/product/doorbells/bkl340lwh). Looks like the output power is 12VDC, 5mA qhish wouldn't work with any Ring doorbells. I'm guessing I need to replace the whole thing with a separate transformer, but wanted to see if I'm missing anything. Any particular transformer recommendations? I don't care about a wires chime as I already have 2 Ring chimes. Thank you!
