Mechanical Door Bell Chime Bypass

I just installed a SimpliSafe Door Bell Pro. Everything is working fine. I’ve selected the option to have the Door Bell Pro ring through the base station, but now it also rings through my old mechanical chime. I’d like to only use the base station as my door bell and stop using the mechanical chime. I’ve investigated the wiring terminal on my mechanical chime and I see a terminal with 3 screw connections. They are labeled Rear, Trans, and Front. There is a Red wire going to the Trans and Front screw terminal. There is also a wire connector with 2 White wires. I tried disconnecting the red wire going to the Front terminal. This stopped the mechanical chime from working and still allowed the base station to ring when the Door Bell Pro button was pushed. However, after several hrs I began getting low battery messages from the Door bell Pro so it seemed like the Pro was not getting constant power , so I reconnected the red wire back to the Front terminal connector. The question I have is whether it’s ok to disconnect both the Front and Trans wires and connect them together. I’m hoping that by doing this I would supply constant power to the Pro and not listen to my old doorbell chime. Any thoughts?
