How to wire Sonoff ZBMINI into a 3 way switch UK

Hi,

I have a setup with 3 switches and was wondering how I can go about wiring it as it is 3 way. I’ve attached a pic corresponding to each of the switches I have access to. Do you happen to know how I could wire in my ZBMINI? I was going to use the switch with the neutrals behind it but I’m not sure where to go from here.

I noticed an old thread on something similar but it was a while back so figured I’d start a new one: Sonoff ZBMINI UK wiring sanity check

Thanks a lot!
