If they are truly that advanced, they certainly already know about us. It seems kind of arrogant to presume that we could detect them with our primitive technology and they could not detect us. Most likely scenario is that they don't care about us in the same way we don't care about ants.
Even sending over a probe at 30% the speed of light would take 400 years, plus another 120 to hear back from it. No matter how interesting, for our human society it would be really hard to raise significant funds for a project that will only pay off in over 500 years, if at all. If they have similar lifespans, such a project might be similarly hard to get off the ground for their society.
That leaves radio communication, but the latest intel they have on us left earth around 1900. At that point we wouldn't have been able to receive anything from them. It's probably questionable if we would have picked something up had they sent a radio signal our way a week ago. Right now SETI might have a radio antenna pointed their way, but that won't last indefinitely, and these events are a bit hard to time from 120 lightyears away.
It's why I'm 100% it can't be advanced life: we can't find life anywhere in the galaxy but we find advanced life in our own backyard (I know 120 light years is quite a lot)?
