How do those $15k/month apartments actually get rented?

So I’ve been apartment hunting and found this insane $15k/month place that I actually want to inquire about. Submitted through StreetEasy like 6 hours ago and radio silence, which is weird because every other place I’ve looked at gets back within an hour or two. Granted I have been typically looking at sub $10k places.

Do I need to go through a broker for these super high end places to even get taken seriously? Like is there some unwritten rule that you can’t just roll up on StreetEasy for luxury rentals. I’m wondering if they think I’m just some rando wasting their time or if there’s a whole different process for these expensive units. And before anyone calls me out yeah I get a $5k housing subsidy which is why I’m even looking in this range, not trying to flex or anything just genuinely confused about the process. Anyone dealt with this before or know how these luxury rentals actually work? The whole thing feels like there’s some secret handshake I don’t know about lol
