MQTT Add On doesn't publish devices from zigbee2mqtt to Home Assistant

I have Zigbee2mqtt and MQTT running as managed add-ons in my home assistant instance on my raspberry pi (running the latest version 2022.11.2).

I have a few devices connected to zigbee2mqtt

but as you can see no device seems to be connected to home assistant through mqtt

can anyone suggest ideas on how to fix that?
