Trying to configure Sonoff LAN and failing miserably

Hello folks, I am new to zigbee and so I have just purchased a Sonoff bridge in the UK and trying to integrate in HA using SonoffLAN integration, but I can’t get it to work as no zigbee devices are found.
When going into the settings of the sonoff bridge, it shows current version as 1.3.0
When reading about it, I note that it talks about zigbee 3.0 protocol. I’m a little confused as to if my bridge is or isnt zigbee 3. I would appreciate any advice.
