Shelly in a 3 way circuit with power at switch 1 but light connected to switch 2

I have the below scenario. I have 120V in my switch 1 box but power is passed to switch 2 through either the black or red traveler wires. I was looking to put a Shelly 1 with the 2nd switch since it directly controls the light but don't have constant power for powering the Shelly 1 L terminal. Does someone have an idea how I can wire this using any of the Shelly devices?
