Make sure you have a recent version of Zigbee2MQTT. If you don't see the same interface as below it is likely you need to update your system.
Open your Zigbee2MQTT control panel and click on the OTA tab.
Find the device that you would like to update and click on "Check for new updates".
After a few moments the "Update device firmware" button will appear if an update is available. Proceed to click on it.
Lastly, confirm the update by clicking "OK".
