Mechanical Chime Does not Work with Eufy E340 Wireless Doorbell 2K Dual Cameras

All:
I recently got the Eufy E340 Wireless Doorbell 2K. I am using a Newhouse Hardware 24V 40VA Door Bell Transformer along with Newhouse CHM24V 24-Volt Wired Doorbell Chime to power both front and rear doorbells on a single transformer and a single chime. I tried everything but cannot get my mechanical chime to “ding”. Has anybody faced a similar issue where the mechanical chime won’t ding. Please help!
