Modify Reolink Doorbell to keep original chime box

I've got the PoE Doorbell on pre-order, but I'm not thrilled about losing my original door chime box. Considering a couple options;
- disecting the receiver and see if I can find something in it to trigger a relay to trigger the chimes
- intercepting the signal between the button and receiver ( https://youtu.be/3utTV8kb01E )
Thoughts? Please don't suggest "just use the new module instead". Looking to have a realistic discussion about this. Thanks.
