Doesn't matter, you'll rewire anyway
Smart switches don't depend on the usual "common + 2 travelers" arrangement. You are going to be re-wiring both boxes to match the requirements of the smart switch.
The only thing you need to identify is the cable between switches (a cable is several wires bundled together in a sheath). Then, assign the colors in that cable according to the instructions. Which will require that you re-define every wire, since these smart switches use the wires completely differently. As such, the prior configuration does not matter.
A common mistake here is to "not read the instructions" and expect it to wire like a common 3-way switch.
Their instructions show the wiring "before", but you only need to concern yourself with cable identification. You'll be re-defining what all the wires do.
Weirdly, their "before" drawings show only 1 traveler. I guess they never got the bulletin on how "conventional" 3-ways work, as they have 2 travelers. Well, it doesn't matter.
