I may be misunderstanding: Are you suggesting a targeted beam to the habitable zone of every star they can see?
If so, I don’t see how that could work, considering that most stars visible at time of transmission would be dead by the time the transmission reaches them. Also the fact that they have orthogonal velocity that would be difficult or impossible to measure and account for.
That was what I was considering. I was hoping the aliens had telescopes that could see the collapsing cloud of gas and work out where the star would end up.

My apologies if I have misunderstood.
