Thats probably not happening at that scale. I know this is the premise of interstellar communication in the three body problem. It's not real.

  Not really, its premise is using our Sun, not some lens composed of 2 galaxies (that would probably misalign well before our signal would reach them), not sure how you came up with such an idea.

    Using things at that scale to talk? It's not a thing in either case.
