Please help on wiring Shelly 1L to two way switch

Ive looked at various threads and youtube vids but still unsure how to wire in a shelly 1l to this setup. One set of flourescent lights with two switches. When I wire in using the wire going to COM as L on the shelly one switch works but the other does not. Please help!

Yeh but still no idea does this mean I have to rewire the existing switches?

It doesn’t match what I have existing wired in the switches though I’m so confused.
