3 wire Auto Gen Start without additional relays or modules (Node Red, Assistants)

Hello all, I’ve noticed that in the Victron auto gen start manual they provide examples of how to convert a 3 wire gen start (like Cummins Onan) to two wire for use with a Cerbo GX for auto gen start.

What is also mentioned is an “Alternative using assistants” in section 2.1 of the manual. I’m wondering if anyone has put this into practice and if its possible to auto gen start a 3 wire start generator without the need for additional time delay relays or modules, maybe using Node Red even?
