OH4.2.3, Zigbee2MQTT problem

Openhabian 4.2.3
RPI 3
Dongle: SONOFF Zigbee 3.0 USB Dongle Plus

Things Ember Coordinator remains in INITIALIZING state
Frontend does not start.

Below I explain what I did:
I installed OH4.2.3 from scratch, and everything that makes up my home automation system.
I added the SONOFF Zigbee3.0 USB Plus dongle in my raspberry.
From Openhabian-config I installed Zigbee2Mqtt.
On Openhab I installed Zigbee Binding add-on.
I started frontend from port 8081 and it works.
I installed the Thing Ember Coordinator as shown in the image:

when I start Ember Coordinator it remains in Initializing and frontail stops working.

Below is the error log:

Can anyone help me to solve the problem?

Your Zigbee coordinator (your Ember USB stick) can be used by only one of zigbee2mqtt or the ZigBee binding, but not both at the same time.

If you choose zigbee2mqtt then you will need to install the MQTT binding in openHAB in order for openHAB to communicate with zigbee2mqtt. (Assuming you already have an MQTT Broker installed, like Mosquitto. If not, you need that too).

If you choose the ZigBee binding then you don’t need anything else as your coordinator will be talking directly with openHAB. But I assume you must uninstall (or at least disable) zigbee2mqtt in this scenario.
