Normal 3-way to smart switch no neutral wire. Is t possible?

Is it possible to connect a simple 3-way switch to a smart switch? The model is a moes go WS-US-RF single L

Which model is it? The 3 way smart switch just replaces 1 of the 3 way switches.
This drawing is not good either way as it show the light on 24/7 :smiley:

Tho looking at their diagrams, a neutral is always needed.
