Shelly 1L tripple switch

I have a bit of a 'complicated' setup and couldn't find an answer to my query yet. Hope someone can share some ideas.

Light bulb(s) connected to 3 switches. Looking to put a Shelly 1L inside the middle ('intermediary') switch seems like the easiest route (below in red), in terms of effort and space to fit in the shelly relay.

As per the diagram, L1 and L2 can be live input & output depending on the situation.

So I am basically trying to replace the physical button ('intermediary' switch in the scheme above) with a software one (Shelly app), while still allowing all physical button to continue operating as usual. Which I think (hope?) is possible.

Still cannot figure out what Shelly ports should I connect 2 in and 2 out wires and what mode should I set the ports to.

Thanks,

Milen

I think I have a solution but can't test it.

But it would be easier at the first switch .

Here's the idea

At first switch

Remove Phase and Black from switch

Connect them (so will be Phase at switch 2)

At second switch

Brown needs to be split in two

- one at SW1 the other at SW2

Black from first switch at L from Shelly

O from Shelly at the Grey (Left side from switch)

Button Type edge

Thanks for your advise SebMai, but that wouldn't that render switch 1 redundant? I'd still like all 3 switches to operate, but also have the software control as well.
