How to Wire a Two Way Switch using Shelly 2PM Gen3?

QUESTION

I have a two way setup in my home that I’m wanting to control with a Shelly 2PM Gen3 or other Shelly.

The SW1 wall switch, have L and N, and the SW2 wall switch don't have L neither N, just the two lines from SW1 and output to lamps.

Is this possible to use a Shelly 2PM Gen3 (or other Shelly) on the SW1 side using the existing wiring I have right now without any new cable? If so how would I physically wire everything together?

Thanks!
