M5Stack Atom Echo - push button to listen

I tried updating my M5Stack today and it no longer works. It appears to be stuck in a boot loop.

Log:

[16:22:54]E (822) esp_image: Image length 1835152 doesn't fit in partition length 1835008
[16:22:54]E (823) boot: OTA app partition slot 0 is not bootable
[16:22:54]E (825) esp_image: image at 0x1d0000 has invalid magic byte (nothing flashed here?)
[16:22:54]E (833) boot: OTA app partition slot 1 is not bootable
[16:22:54]E (839) boot: No bootable app partitions in the partition table

If I understand correctly, the package I was using was:
m5stack.atom-echo-voice-assistant: github://esphome/firmware/voice-assistant/m5stack-atom-echo.yaml@main

I was able to successfully update it with the process detailed here.

With this version, I’m not able to do something that I liked from my previous version - use the push button to initiate listening instead of using the wake word. My family did a lot better with that than remembering another wake word (since we already use Alexa…)

Is there a way to restore that functionality? I don’t understand enough about ESPHome’s YAML editing to know how/if I can do this.
