Question about Shelly Dimmer 2

Hello, I just want to switch the dimmer on and off with 2 switches, I don't need the dimming function. Now my problem is that the switches switch digitally, so they don't have a mechanical on/off function. They also require a low current for the indicator lamp and I can't get the circuit to work. Regardless of whether the switches get the L line from Dimmer2 or go directly from L to the S1/ S2 connections, they never switch the Shelly. What do I have to change to make this work?
