Zigbee2MQTT and Synology DS920+ on 7.2, problem after Synology upgrade

In the container gladys-z2m-zigbee2mqtt, the dongle’s port is always /dev/ttyACM0 (that was to make configuration easier).
You will still find in /var/lib/gladysassistant/zigbee2mqtt/z2m/configuration.yaml

serial:
  port: /dev/ttyACM0

The mapping between the host port (the real one) and the container’s is indeed done when the container is created (or on reactivation if there’s a change).

"Devices": [
    {
        "PathOnHost": "/dev/ttyUSB0",
        "PathInContainer": "/dev/ttyACM0",
        "CgroupPermissions": "rwm"
    }
],

I created an issue, I can take a look.
