Finding Newly Added Properties

I was searching for properties in the Caribbean the other day and stumbled across a property called "Paradise Beach, Nevis"

https://www.hilton.com/en/hotels/nevpblx-paradise-beach-nevis/?flexibleDates=false&numRooms=1&numAdults=1&numChildren=0&room1ChildAges=&room1AdultAges=&sessionToken=6ecced44-4174-4f12-8559-cfa30cc7919f

There's no availability (yet), which indicates to me that this is obviously a newly added property. Plus, I would have definitely remembered it from previous searches.

Which leads me to my question - does anyone know of a way to search/find newly added properties, especially SLHs? I know that only ~450 out of ~700 SLH properties are bookable through Hilton, and I'm always interested to know when new ones are onboarded.
